    Conformational analysis of diastereomeric &alpha;-amino nitriles [1S,2R,(S)]- and [1S,2R,(R)]-N-cyanophenylmethyl-1-aminoindan-2-ol [(S)-1 and (R)-1] has been carried out at the DFT B3LYP/6-31G* level. It was found that these compounds consist of tens of conformers: There are three stable conformations S1&ndash;S3 for (S)-1 within a narrow energy window (0.4 kcal/mol) with the population being 43% (S1), 24% (S2), and 22% (S3), respectively (Table 1). On the other hand, the global minimum conformation of (R)-1 (R1) is more than 1.51 kcal/mol more stable than the other conformations and occupies 76% of the population (Table 2). The difference in the total energy between the two diastereomers is small (&Delta;E = &ndash;0.09 kcal/mol), which is in reasonable agreement with the fact that the two diastereomers equilibrate with a ratio of 50:50 in DMSO. On the contrary, it has been shown that (S)-1 is more stable than (R)-1 in the crystal form. The crystal-state conformation of (S)-1 (S0) determined by an X-ray crystallographic analysis agrees well with S3 (Figure 1, Table 3). In the crystals, one molecule binds to four neighboring molecules with hydrogen bonds (Figure 2b). In addition, the crystal density of (S)-1 is higher than that of (R)-1. These observations suggest that the S3 molecules are packed tightly together to form, with assistance of the intermolecular hydrogen bonds, a stable crystal. On the other hand, the crystal-state conformation of (R)-1 (R0) is different from R1 with regard to the conformation of the phenyl moiety, as well as the mode of an intramolecular hydrogen bond (Figure 1, Table 3). Taking account of the low crystal density of (R)-1, it seems that R1 is not likely to crystallize in its conformation. Therefore, the R1 molecules are assumed to change the conformation and the hydrogen-bond mode upon crystallization to narrowly form a not so stable crystal.

    From the viewpoint of reducing environmental load and economic efficiency, the development of a simple and precise method for separating a mixture that cannot be separated by crystallization and/or distillation is eagerly desired. We previously found that crystals of p-tert-butylcalix[4]arene with a bowl-shaped structure, upon being immersed in a difficult-to-separate mixture, selectively absorb a particular compound, thereby achieving separation. In this study, we have designed and synthesized novel open-chain molecules for this separation method and shown that they can be used for the separation of amines, alcohols, and carboxylic acids.

    Ligands with highly preorganized coordination environment are necessary for the development of high-performance metal extractants, high-sensitivity sensors, and highly functional metal-complex catalysts to attain high affinity and selectivity toward metal ions. In this study, we synthesized OH-X hybrid-type calixarenes having two coordinating functional groups X instead of two distal OH groups of p-tert-butylcalix[4]arene by our previously developed method and evaluated their recognition abilities toward metal ions. By positioning metal ions near the calix framework, we could create high-performance and highly selective metal extractants, palladium complex catalysts showing unprecedented selectivity, and a highly sensitive and highly selective mercury sensor.

    Crystals of calix[4]arene and thiacalix[4]arene exhibit distinct differences in inclusion properties towards primary alcohols, which originated from the difference in the crystal packing of inclusion crystals according to the property of bridging groups. Selective inclusion of methylamines and switching of guest selectivity by solvent polarity using crystals of thiacalix[4]arene are achieved. It is found that the property of crystals of calix[4]arene can be applied to selective inclusion of aromatic regioisomers. Furthermore, synthesis of linear carboxylic acid-type host molecule having a 2,2'-thiodiphenol structure and selective inclusion of amine isomers using it are succeeded.

    As CO2 is an abundant, inexpensive, and renewable carbon source, the development of a method for its synthetic use is one of the most important subjects in green sustainable chemistry. Recently, we have found that CO2 can be activated by the combined use of AlX3 and R3SiX. By examining this phenomenon and extending its principles, we have succeeded in the activation of CO2 with R3SiB(C6F5)4 and its applications to the carboxylation of aromatic compounds and the hydrocarboxylation of olefins.

    1.無溶媒および溶媒蒸気との接触条件下でのエピ化晶出の適用性の検討 前年度に検討した(1S,2R)-1-アミノインダン-2-オールと種々のアルデヒドとのStrecker反応で合成したα-アミノニトリルの無溶媒エピ化晶出について,溶媒蒸気の種類や溶媒の蒸気圧がエピ化速度に与える効果を詳細に検討した。その結果,飽和蒸気圧の80%の蒸気量でも,室温付近で十分に反応が促進されること,溶媒としてはメタノールやアセトニトリルが良いことなどがわかった。また,アルデヒドに導入した置換基の種類によっては,エピ化と同時に一方のジアステレオマーの選択的な分解も認められた。また,本エピ化晶出法の適用性を調べたところ,抗高血圧薬Lotensinの合成鍵中間体であるアミノラクタム4,5-ジヒドロ-3-[(S)-1-フェニルエチル]アミノ-1H-ベンゾ[b]アゼピン-2(3H)-オンのジアステレオマー結晶混合物も定量的にエピ化することがわかった。 2.誘電率制御分割と無溶媒エピ化晶出の融合の可能性の検討 誘電率制御分割が可能なことがわかった1,1'-ビナフタレン-2,2'-ジカルボン酸のモノ(S)-1-フェニルエチルアミドと,ロイシンの(S)-1-フェニルエタンスルホン酸塩について,エピ化晶出への適用を検討した。その結果,後者については,サリチルアルデヒドとp-トルエンスルホン酸を添加することでエピ化が起こり,D-ロイシン塩の分割効率を向上させることができた。しかし,L-ロイシン塩が晶析する誘電率条件下でもD-ロイシン塩が析出し,溶媒の誘電率により優先して晶析する塩は変化しなかった。

    申請者は, ラン科の植物中に含まれる生理活性1, 1'-ビフェナンスレン型天然物Blestriarene C(1)が, 自然光や蛍光灯の照射下に極めて容易にラセミ化することを見出している。本研究の目的は, 本ラセミ化反応の反応機構を解明するとともに, この現象を新しいフォトクロミズム系へ展開するために, 脱ラセミ化について検討することである。 1. 1とその類縁体のラセミ化には, 光照射された1が酸素により酸化されてカチオンラジカルを生じる過程があり, 酸化還元電位の低いものがラセミ化しやすいと考えられるが, ラセミ化活性と酸化還元電位との相関性は必ずしも高くなかった。この原因が, 試料中に含まれる微量の不純物がラセミ化を抑制するためであることを突き止めた。このことと溶媒の工夫により, 単純なビフェナンスロール類でも十分なラセミ化活性が得られることがわかった。また, 試料の酸化により生じると考えられる不純物にはキラリティーが存在することから, その性質を利用してラセミ体の1(またはその類縁体)を脱ラセミ化できる可能性がある。 2. 1の7, 7'-ジエーテル体2をキラル化合物との包接錯体を形成させて脱ラセミ化させる方法を検討し, シクロヘキサン-1, 2-ジアミンが, NMRでも判別可能なジアステレオメリックな包接錯体を形成することを見出した。円偏光照射による脱ラセミ化は, 現有の円二色性分散計の精度が足りないことがわかったので, 今後, より精密な測定を行っていく予定である。 3. 脱ラセミ化への展開を期待して, アトロプ異性体の光学分割とエピ化の容易なα-アミノニトリルの動的速度分割についても検討した。

    申請者は,CO_2をLewis酸で活性化し,有機化合物へ親電子的に固定化する方法について研究しており,AlBr_3の存在下,トルエンのCO_2によるカルボキシル化が,過剰量のMe_3SiXの添加により著しく促進されることを見出している。本研究の目的は,本反応の反応機構を検証し,その原理を抽出して新しい高度分子変換法へ展開することであり,今年度は,下記の成果を得た。 1. トルエンのCO_2によるカルボキシル化におけるシリル化剤の反応促進効果は,シリル化剤が活性種と考えられるCO_2とAlからなる錯体をよりいっそう活性化するためであることが昨年度の研究により示唆されたが,このことがIRによる活性種の分析でも支持された。また,CO_2圧下,R_3SiClとAlBr_3を反応させて得た反応混合物を用いると,窒素下でもトルエンを30%程度の収率でカルボキシル化できることを見出した。 2. N-上に置換基を有するピロール類およびインドール類が,Me_2AlClの存在下に,CO_2で容易にカルボキシル化できることを見出した。 3. CO_2を選択的かつ強く活性化する金属錯体を設計することを最終的な目標として,種々のモノおよびビスチアカリックス[4]アレーン類を合成し,チタンとの錯形成能を評価した。 4. ケイ素上に種々の置換基を有するシリルアミンR_3SiNR'_2とAlCl_3を用いて,N-メチルピロール,N-メチルインドールを良好な収率でシリル化できることを見出した。また,シリルクロリドR_3SiClをAlCl_3,^iPr_2EtNとともに用いると,シリルアミンを用いた場合に比べて収率が向上した。 5. 班員間共同研究により,1,1'-ビナフタレン-2,2'-ジカルボン酸の誘電率制御分割に成功した。

    本研究の目的は,二酸化炭素をLewis酸で活性化し,芳香族基質へ親電子的に固定化する反応について,その最適化を図り,基質の適用性を調べること,本反応を将来的にオレフィン類への二酸化炭素の固定化に展開するために,二酸化炭素を選択的に活性化するLewis酸を設計・合成することであり,下記の成果を得た。 1.臭化アルミニウムとクロロトリメチルシランの存在下にトルエンのカルボキシル化の反応条件を最適化することで,最高96%の収率でトルイル酸(オルト:パラ=1:6)を得ることができた。また,キシレン,メシチレン,ナフタレンなど他のアレーン類でも,良好な収率でカルボン酸が得られた。反応のマスバランスの検討から,本反応の機構として,ルイス酸によるタンデム型in situ Friedel-Craftsシリル化-炭酸化,またはシリルカチオンがLewis酸として作用し,活性種と考えられる二酸化炭素-アルミ錯体をよりいっそう活性化し,一段階で炭酸化する機構が考えられる。反応機構を明らかにし,新しい反応へ展開したい。 2.本研究の反応には,非常に強いLewis酸であるハロゲン化アルミニウムのみが活性を示し,このことが反応の適用性を制限している。そのため,二酸化炭素を選択的に活性化できるLewis酸の開発が望まれる。そこで,チアカリックス[4]アレーンをべ一スとし二酸化炭素の二つのカルボニル基に同時に二点配位できる四核Ti (Iv)錯体をデザインした。この配位子の合成には,チアカリックス[4]アレーンの一つの水酸基を三価のアミノ基に変換する必要があるが,従来,カリックス[4]アレーン類の水酸基をアリールー酸素結合を切断して他の官能基に変換することは,その立体的な理由から極めて困難であった。今回,Ullmann型反応により,モノアミノ置換体を初めて実用的な収率で合成することに成功した。

    In this study, we have synthesized blestriarene C (2,2',7,7'-tetrahydroxy-4,4'-dimethoxy-1,1'-biphenanthrene) and its analogs by using an ester-mediated nucleophilic aromatic substitution as a key step and investigated their photoracemization under fluorescent light exposure. Racemization of 1,1'-binaphthalenes and deracemization of blestriarene C were also examined. Blestriarene C was found to racemize by exposing its solution to the light near the ^1L_b absorption band. Removal of oxygen from the solution significantly retarded the reaction, suggesting intermediary of oxygen in the racemization. Blestriarene C analogs lacking 4,4'-dimethoxy and/or 7,7'-dihydroxy groups did not racemize under the conditions, while the 7,7'-diisopropoxy derivative, as well as the unsymmetrical biphenanthrene lacking 4'-methoxy and 7'-hydroxy groups, easily racemized. The tendency toward the racemization was found to strongly correlate with the redox potential of the compounds by cyclic voltammetry (CV) experiments. Thus, the lower redox potential the compound has, the higher racemization activity it shows. Based on these observations, we proposed a feasible reaction mechanism, which involves one-electron oxidation of blestriarene C by oxygen with the aid of the fluorescent light to form a radical cation intermediate. 1,1'-Binaphthalenes having two or three hydroxy and/or methoxy groups in total on each naphthalene half did not racemize under the same conditions. These compounds did not show reversible redox behavior on the CV spectra, which should be crucial in the photoracemization.

    当研究の目的は新規ホスト分子チアカリックスアレーン(TCA)の易水溶性分子に対する包接能を活用し,その高効率分離回収法の可能性を検討するところにある.前年度までに1.ゲスト分子の適用限界の調査,2.包接機構の解明を行った.本年度は3.TCAの分子修飾による包接能の高度化を検討した. 3.TCAの分子修飾による包接能の高度化 TCAは溶液中でコンホメーション変換運動をしており,これは易水溶性分子の包接能を弱めていると予想できる.そこで分子修飾を施し,コンホメーションの動的な揺らぎを制限することを企図した.まず,分子修飾としてTCAのフェノール性OHの一つをアルキル化し,OCH_2COOHとした.アルコールやケトン,ニトリルなど水溶性ゲストに対する包接能を調べた.TCAの場合より大きなゲスト分子に対して高い包接能を示したが,TCAモノカルボン酸はより小さなゲストに対し,高い包接能を示した.特にメタノールに対し10^2M^<-1>を越える大きな包接能を示した。これはモノアルキル化の結果,空孔の形状が制御され,あるいは空孔サイズが制限され,小分子の包接に適合したと考えた.一方大きなゲスト分子は生成したホストゲスト錯体において疎水的アルキル部位を空孔の外に露出するため,不安定となると考えた. 一方,TCAの最大の特徴である,金属イオンとの錯形成能を利用し,TCAのフェノール部位を固定した.Cu(II),Cd(II)イオンのTCA錯体について易水溶性分子の包接能を評価した.その結果TCAに比べ,錯体は一桁程度の包接能の向上を示すことがわかった.これは統計的な効果を上回る包接能の向上であり,コンホメーション固定の効果と考えられる. 以上から易水溶性分子のホスト設計の指針が得られ,これを塩析などの相転移と組み合わせれば,易水溶性分子の分離回収技術の開発につながると考えられる.

    Aminothiacalixarenes, new members of the thiacalixa[4]arene (TCA) family having amino functions at the lower rim, were prepared from sulfur-oxygenated derivatives of TCA by applying the chelation-assisted nucleophilic aromatic substitution (S_NAr) reaction to estimate their intrinsic abilities for developing novel functional materials. 1.Selective syntheses of tetraamino, 1,2-and 1,3-diamino, and monoamino TCAa were achieved by using the S_NAr reaction on tetra-O-methylsulfonyl-and sulfinylcalix[4]arenes by lithium amides as the key step. Conformational analysis of the substrates indicated that the methoxy groups in a cis relationship with at least one adjacent sulflinyl group selectively underwent the S_NAr reaction. 2.Inclusion behavior of tetraamino TCA was investigated by crystallizing the host molecule from a series of solvents. It was found that the compound selectively formed 1:1 complexes with acetonitrile and dichloromethane. The acetonitrile complex adopted a cone conformation, while the host molecule crystallized out in a 1,3-alternate information from methanol without forming any inclusion complex, indicating that the complexation was accompanied by the conformational change of the host molecule (induced fit to the guest molecule). 3.Complexation ability of tetraamino TCA was investigated by solvent extraction experiments. It was found that tetraamino TCA served as a highly specific extractant for Au(III) and Pd(II) ions. The X-ray crystallographic analysis of a Pd(II) complex indicated that tetraamino TCA ligated is the metal ion with the bridging sulfur atoms and deprotonated amino functions. On the other hand, 1,2-diamino TCA was found to flexibly ligate to soft and hard metal ions by changing the ligation site (NH_2,OH). 4.Derivatization of the amino TCAs gave tetra(N-ethoxycarbonylmethyl) and bis(salicylideneamino) derivatives. The amino groups of amino TCAs were displaced with iodine atoms via the diazonium salts.

    1.[2+2] Cycloaddition reaction of carbonyl compounds with ketene The [2+2] cycloaddition reaction was examined by using some cationic group 8-10 transition metal complexes as the catalysts, among which palladiun and platinum complexes showed good perfonnance. It was found that the catalytic activity was greatly affected not only by the metal center and the ligand but also by the counter anion. Attempts on asymmetric induction by using chiral ligands failed but chiral counterions, tetraalkoxy borates derived from substituted BINOLs, were found to serve as a chirality-recognizing element in the asymmetric reaction. 2.Tandem [242] cycloaddition-allylic rearrangement or α,β-unsaturatead carbonyl compounds with ketene In the reaction of α,β-unsaturated carbonyl compounds, 4-vinyloxetan-2-ones generated by the cycloaddition oflen rearrange under the conditions to give 3,6-dihydro-2H-pyran-2-ones. Thus, the reaction of a series of α,β-unsaturated aldehydes and ketones with ketene was examined to deduce the origin of the rearrangement. It was found that the reaction occurs if 4-vinyloxetan-2-ones bearing an alkyl substituent at the 4-position or at the 2-position of the vinyl moiety are generated in the cycloaddition. Based on the observations, a reacfion mechanism was proposed, which includes a zwitterion generated by heterolytic cleavage of the C(4)-0 bond of the 4-vinyloxetan-2-one as an intermediate. Asymmetric induction with up to 57% de has been achieved by using α,β-unsaturated aldehydes bearing an asymmetric carbon center at the β-position. 3.Activation of CO_2 by Lewis acids and its chemical fixation to carbon-carbon double bonds As an extension of this research project, a possibility was examined to activate C0_2 by aluminum-based Lewis acids and fix it electrophilically to aromatic compounds and organosilanes, which might lead to an alternative method to prepare oxetan-2-ones from olefins and CO_2 in the future.

    We have investigated regioselective syntheses of multisubstituted aromatic compounds via the ester-mediated nucleophilic aromatic substitution(S_NAr)and the conjugate addition to benzoate rings. 1.The S_NAr reaction of 2-methoxybenzoates with Grignard reagents was found to be accelerated by introduction of a methoxy or halo substituent at the 3-position of the benzoate ring. The ligating ability of the 3-methoxy group was found to play a crucial role in enhancing the reactivity of the 2-methoxy moiety, while the electron-withdrawing ability was more important in the case of the halogens. 2.A stepwise S_NAr reaction of 2, 6-dimethoxybenzoates with two kinds of Grignard reagents was achieved by controlling the molar equivalence of the Grignard reagents to the substrates, giving the corresponding benzoic esters with different substituents at the 2- and 6-positions. Novel chiral alcohols, 1, 8-disubstituted fluorenols and 7-substituted 2, 2-dimethyl-1-indanols were conveniently synthesized by using the process and evaluated for their chiral induction abilities. 3.Novel ternaphthalenes were synthesized by the S_NAr reaction between 1, 5-(or 1, 4-)dialkoxynaphthalen-2, 6-(or 2, 3-)dicarboxylic esters and 1-naphthyl Grignard reagents or 1-alkoxy-2-naphthoic esters and naphthalen-1, 4-di-Grignard reagents. 4.A regioselective allylation of 3-bromo-2, 6-dimethoxybenzonic ester at the 2-position was achieved and utilized for a facile preparation of 5-bromo-8-methoxy-3-methylnaphthalen-1-ol, which is a key compound for the syntheses of michellamines. 5.A combination of the estermediated S_NAr reaction and the conjugate addition to benzoate rings made it possible to introduce three different substituents at the 2-, 4- and 6-positions of a 3-bromo-2, 6-dimethoxybenzoate, which was utilized for the synthesis of a larreantin analog. 6.A biphenyl-2-carboxylic ester, which had been prepared by the S_NAr reaction, was successfully utilized as a key synthetic intermediate for blestriarene C.7.Calix[4]arenes comprised of four aniline units were synthesized for the first time via the S_NAr reaction of tetramethyl ether of sulfinyl- or sulfonylcalix[4]arene with lithium benzylamide.

    We have developed diastereoselective asymmetric reactions using the 2,2'-positions of 1, l'-binaphthyl compounds as a chiral field. Synthesis of novel binaphthyls and thiacalixarenes and exploration of the functions of the latter compounds are the other targets of this research. The summary of the results is itemized as follows : 1. Treatment of gamma-keto esters of l , 1'-binaphthyl-2-ol bearing an appropriate oligoether tether at the 2'-position with DIBAL-H in the presence of magnesium bromide gave, after LAH reduction of the resulting diastereomeric hydroxy esters, I , 4-diols with high enantiomeric excesses. On the other hand, Grignard reaction of the relevant gamma-keto esters gave gamma-lactones having a chiral quaternary carbon center with up to 99% ee. 2. The remote asymmetric inductive Grignard reaction was found to be applicable to delta- and epsilon-keto esters and was advantageously utilized for the synthesis of a marine antibiotic, malyngolide. 3. The corresponding Grignard reaction of zeta- to theta-keto esters was realized by using BINOL as the chiral auxiliary. Thus, the Grignard reaction of the mono omega-keto esters of BINOL in the presence of magnesium bromide proceeded with more than 80% de. 4. Several binaphthyl compounds were effectively prepared in an atropisomeric or racemic form via the nucleophilic aromatic substitution on 1-alkoxynaphthalenes bearing an ester, sulfonyl, or nitro group at the 2-position as the activating group by 1-naphthyl Grignard reagents. 5. A novel calixarene, p-tert-butylthiacalix[4]arene, which is expected to be a potential substitute for BINOL framework, was effectively prepared from p-tert-butylphenol and powdered sulfur. The derivatives were found to function as a host molecule to bind specific metal ions and toxic halogenated organic compounds and as a chirality-recognizing element for a stationary phase for gas chromatography.

    Although nucleophilic aromatic substitution reaction (S_NAr) is an important process in organic synthesis, it generally requires severe reaction conditions and/or the presence of highly electron-withdrawing, so-called "activating" groups on the aromatic nucleus, which limits its applicability. We have investigated the chelation-assisted S_NAr reaction mediated by unclassical activating groups and obtained the following results. 1.The reactions of 2,6-di-tert-butyl-4-methoxyphenyl 2-methoxybenzoate with several organometallics were found to give the methoxy-substitution products and/or the conjugate addition products to the benzoate ring, preferring the latter products at the expense of the former with the increase of the electron-donating ability of the carbanion species. 2.The S_NAr reactions were found to be accelerated by introducing a substituent which could ligate to the metal center of the nucleophiles into the 3-position of the benzoate ring. 3.Facile synthesis of O-methylhamatine was achieved by the asymmetric biaryl coupling reaction of a chiral 1-menthoxy-2-naphthoate with an aryl Grignard reagent as the key step. 4.Chiral cyclophanes and an acetal were employed as the substrate of the S_NAr reaction and highly efficient conversions of chiral elements among C-centro-, planar and axial chirality were attained. 5.Triarylamines were conveniently prepared by the reaction of a 2- or 4-fluorobenzoate with lithium diarylamides. 6.Novel chiral alcohols, 1,8-disubstituted fluorenols and 7-substituted 2,2-dimethyl-1-indanols were synthesized via the S_NAr reaction and resolved. The latter were proved to be highly resistant to racemization and could effectively be utilized as chiral auxiliaries. 7.2-Sulfonyl-as well as 2-sulfinyl-substituted 1-methoxynaphthalenes were found to undergo the S_NAr reaction. Factors affecting the activating power of the 2-substituents were elucidated. 8.Chiral aminophosphines were prepared via the S_NAr reaction of 2-diphenylphosphinoyl-1-methoxynaphthalene with chiral lithium amides, followed by reduction of the phosphinoyl function. They could effectively be utilized as the ligands for palladium-catalyzed allylic substitution reaction.

    1.1,12-ジオキサ[12](1,4)ナフタレノファン-14-カルボン酸(1)のイソプロピルエステルへの2-置換-1-ナフチルGrignard試薬の芳香族求核置換(S_NAr)反応により、1,1′-ビナフチル-2-カルボン酸エステル類を収率良く得ることができた。この際、基質であるナフタレノファンの面不斉が>99〜91%eeの効率で軸不斉に変換されることを見い出した。本反応は、シクロファンの面不斉を他の不斉要素に変換した初めての例である。また、誘導される軸の絶対配置をCDスペクトルから帰属し、先に提案した1-(-)ーメントキシ-2-ナフトエ酸エステルに対するS_NAr反応の不斉誘導機構を支持する重要な知見を得た。 2.(RS)-1の(-)ーメンチルエステルを(-)ーメントキシドのS_NAr反応により、速度分割することを試みた。その結果、選択性は最高でも31%deと低かったが、メントキシドの中心性不斉によりナフタレノファンの面不斉を識別できることがわかった。 3.光学的に純粋な2-メチル-1,3-ベンゾジオキソ-ル-4-カルボン酸エステルへの2,6-二置換フェニルリチウムのS_NAr反応により、6-ヒドロキシビフェニル-2-カルボン酸エステルを合成できた。この際、60%ee程度不斉収率が得られたが、生成するビフェニル類は精製段階でラセミ化しやすく、実際にはさらに高い効率で、アセタール上の中心性不斉がビフェニルの軸不斉に変換されているものと考えられる。 4.(3-ブロモブトキシ)-2-(-)ーメントキシ安息香酸エステルを合成し、これを金属マグネシウムと処理することにより分子内S_NAr反応を検討したが、期待した生成物は得られなかった。従って現在のところ、炭素中心性不斉から炭素中心性不斉への変換は成功するに至っていない。

    1.1-メトキシ-2-ジフェニルホスフィニルナフタレンへの光学活性なアミン[例えば(S)-1-フェニルエチルアミン、(S)-N-メチル-1-フェニルエチルアミン、(R,R)-2,5-ジメチルピロリジンなど]のリチウムアミドやアルコール[例えば(S)-1-フェニルエチルアルコール、(-)ーメントールなど]のナトリウムアルコキシドを求核試薬とする芳香族求核置換反応により、新規なジフェニル(1-置換-2-ナフチル)ホスフィン類を合成した。また、(S)-N-メチル-1-フェニルエチルアミンなどC_2-対称でないアミンから合成されたアミノホスフィン類には、アミノ基の窒素原子とナフタレンの1-位炭素原子間の束縛回転に由来する配座異性体が存在することを見い出した。 2.1.で合成したアミノホスフィン類を配位子とするニッケル錯体がビニルブロミドと1-フェニルエチル Grignard 試薬とのクロスカップリング反応の触媒となることを見い出した。しかし、分子内カップリング反応は現在のところ、成功するには至っていない。 3.1.で合成したアミノホスフィン類を配位子とする金属錯体を用い、アリルエステル類の置換反応や蟻酸還元、スチレンのヒドロホルミル化やヒドロホウ素化、アセトフェノンのヒドロシリル化など種々の触媒反応を検討した。その結果、(S)-1-フェニルエチルアミンから誘導された配位子のロジウム錯体によるヒドロシリル化で40%ee程度、(R,R)-2,5-ジメチルピロリジンから誘導された配位子のパラジウム錯体によるアリル置換反応で60%ee程度の不斉収率が得られた。また、蟻酸還元反応でも良好な収率で末端オレフィンが得られており、本研究で合成したアミノホスフィン配位子は、一座にも二座にもなり得ることが分かった。

    芳香族求核置換(S_NAr)反応は一般に起こり難い反応であり、厳しい条件下で反応を行うか、強い電子吸引基を活性化基として導入する必要がある。しかるに、先に申請者らは、エステル基がo-位アルコキシル基をS_NAr反応に対して強く活性化することを見い出した。このことから、ホスフィニル基(P(=O)R_2)、スルホニル基(S(=O)OR)などのリンまたは硫黄原子団も同様の反応の活性化基となり得ることが期待されるが、従来このような反応は全く知られていなかった。本研究では、これらの官能基を活性化基とするS_NAr反応について検討し以下の成果を得た。 1.2-位にジフェニルホスフィニル基を配した1-メトキシナフタレンへのGrignard試薬、アルコキシド、リチウムアミドなどの炭素、酸素、および窒素求核試薬の反応を検討し、これらの試薬がいずれも温和な条件下で芳香族求核置換反応を起こすことを見い出した。生成物は、キシレン中、トリクロロシランで還元することにより、トリアリールホスフィン類に誘導できた。 2.1.の方法により、近年注目されつつあるビナフチル型単座ホスフィン配位子である2^′-メトキシ-2-ジフェニルホスフィノ-1,1^′-ビナフチル(MOP)の簡便な合成法を確立した。 3.t-ブチルスルホニル基も1.と同様の芳香族求核置換反応の良好な活性化基となることを見い出した。t-ブチルスホニル基は、o-位のメタル化を促進すること、また最近、ニッケル触媒存在下でLiA1H_4による還元、Grignard試薬による置換が容易に起こることが報告されており、本研究の反応を利用することによりアリールt-ブチルスルホンを出発物質とする多置換芳香族化合物の選択的な合成法が確率できるものと期待される。

    芳香族求核置換反応は重要な反応であるが一般には厳しい反応条件、あるいは基質に制約があるなどの問題点がある。さきに我々は、o-位のエステル基がアルコキシル基を芳香族求核置換反応に対して著しく活性化するという化学反応論的にも合成化学的にも重要な新事実を見出し、o-アニス酸エステルとフェニルGrignard試薬との反応によるビフェニル誘導体の簡便な合成法を確立した。本研究では、本芳香族求核置換反応の適用と限界を明かにすることを目的とし、研究計画に従ってフェニルカルバニオンばかりでなく、炭素、酸素、および窒素求核試薬によるアルコキシ安息香酸エステル類の反応を詳細に検討し、以下の成果を得た。 1.炭素中心求核試薬として、アルキルGrignard試薬やリチウム試薬も有効であり、o-アルキル、またはアリール置換安息香酸を簡便に調製することが出来る。特に、有機リチウム試薬は-78℃の低温でも短時間に高収率で置換生成物を与えた。 2.上記置換反応を軸不斉ビフェニル誘導体の不斉合成に応用することを検討した。その結果、o-(-)-メントキシ安息香酸エステルとo-置換フェニルGrignard試薬との反応で、最高80%に達する光学収率で軸不斉ビフェニルが不斉合成出来た。得られた数種の新規な光学活性ビフェニル誘導体の絶対配置は、さきに我々の開拓した分子内不斉Ullmannカップリング反応により決定することが出来た。 3.酸素中心求核試薬としては1級、または2級アルコールから得られるアルカリ金属アルコキシドを、窒素中心求核試薬としては1級、または2級アミンのアルカリ金属アミドを用いて、効率よく上記芳香族求核置換反応を行うことが出来た。 以上、エステル基を活性化基とする芳香規求核置換反応は合成化学的にもきわめて有用であり、今後の発展が一層期待される。
