Abstract A convenient scaleable process for the preparation of substituted phenylglycines 2 by a modified Strecker reaction is described. Bisulfite-mediated addition of benzylamine and cyanide anion to substituted benzaldehydes 3 gave the aminonitriles 4 which were hydrolysed in two steps to the N-protected amino acid 1. Debenzylation using catalytic transfer hydrogenation gave the title compounds
摘要 描述了通过改进的 Strecker 反应制备取代的苯基甘氨酸 2 的方便的可扩展方法。亚硫酸氢盐介导的苄胺和氰化物阴离子与取代的苯甲醛 3 的加成得到氨基腈 4,该氨基腈 4 分两步水解为 N-保护的氨基酸 1。使用催化转移氢化的脱苄基以良好的产率得到标题化合物。
