(-)-(R,E)-2-hydroxy-3-pentenenitrile 1, obtained by R-oxynitrilase catalyzed addition of HCN to 2-butenal, was shown to be an excellent chiral starting material for the synthesis of alpha-hydroxy-beta-amino acids of high enantiomeric and diastereomeric purity. The synthesis of N-benzyl (S)-isoserine 7a and (2S,3S)-isoallothreonine 7b, as well as N-benzoyl (2S,3S)-3-phenylisoserine 14 is reported. Copyright (C) 1996 Elsevier Science Ltd
(-)-(R,E)-2-羟基-3-戊烯腈 1 是通过 R-氧腈合酶催化的 HCN 加成到丙烯醛上而得到的,可作为合成具有高对映体和双对映体纯度的 α-羟基-β-氨基酸的优秀手性起始材料。本文报道了 N-苄基 (S)-异丝氨酸 7a 和 (2S,3S)-异白氨酸 7b,以及 N-苯甲酰 (2S,3S)-3-苯基异丝氨酸 14 的合成。版权 (C) 1996 Elsevier Science Ltd。
