  简单高效的光学纯α-芳基甘氨酸的非对映选择性Strecker合成

  摘要：

  报道了一种简单且经济的方法，用于合成高度官能化的α-氨基腈，即具有高光学纯度的α-芳基甘氨酸的前体。为此，在1，3斯特雷克反应中将（R）或（S）-2-氨基-2-苯基乙醇用作手性助剂。用广泛的试剂系统研究了反应，以生成氰基亲核试剂。方法已扩展到合成（S）-α-（2-碘-5-硝基苯基）甘氨酸，（S）-α-（4-甲氧基苯基）甘氨酸和（R）-β-（4-甲氧基苯基）丙氨酸。

  The high diastereoselectivity achieved in Strecker synthesis using inexpensive α-phenylglycinol as chiral auxiliary and its facile removal by oxidative cleavage make it an ideal choice for the large scale preparations of optically active α-amino acids specially α-arylglycines present abundantly in glycopeptide antibiotics. A number of chiral amino acids are synthesized following this method. Also molecular

  使用廉价的α-苯基甘氨醇作为手性助剂，在Strecker合成中实现了很高的非对映选择性，并且通过氧化裂解可轻松去除，这使其成为大规模制备旋光性α-氨基酸（尤其是糖肽类抗生素中大量存在的α-芳基甘氨酸）的理想选择。按照这种方法可以合成许多手性氨基酸。还进行了分子力学计算以解释观察到的非对映选择。

  A practically simple three-component Strecker reaction for the asymmetric synthesis of enantiopure alpha-arylglycines has been developed. Addition of a range of aryl-aldehydes to a solution of sodium cyanide and (S)-1-(4-methoxyphenyl)ethylamine affords highly crystalline (S,S)-alpha-aminonitriles that are easily obtained in diastereomerically pure form. Heating the resultant (S,S)-alpha-aminonitriles in 6 M aqueous HCl at reflux resulted in cleavage of their chiral auxiliary fragments and concomitant hydrolysis of their nitrile groups to afford enantiopure (S)-alpha-arylglycines. The enantiopurities of these (S)-a-arylglycines were determined via derivatization of their corresponding methyl esters with 2-formylphenylboronic acid and (S)-BINOL, followed by H-1 NMR spectroscopic analysis of the resultant mixtures of diastereomeric iminoboronate esters.

  the synthesis of highly functionalised α-amino nitriles, precursors to α-arylglycines with high optical purity is reported. For this purpose, (R) or (S)-2-amino-2-phenylethanol were used as chiral auxiliaries in a 1,3 Strecker reaction. Reactions were studied with a broad range of reagent systems for the generation of cyano nucleophile. Methodology has been extended for the synthesis of (S)-α-(2-i
