N-protected α-amino epoxides of erythro configuration, derived from α-amino acids, were synthesized in a stereoselective manner. The erythro (2S,3S) configu- ration was achieved by the synthetic sequence: amino acid → haloketone → halohydrin → epoxide. A mechanistic explanation for the observed stereoselectivity is presented. This stereoselective synthetic approach was applied to the synthesis of a
以立体选择性方式合成衍生自α-氨基酸的N-保护的赤型构型的α-氨基环氧化物。所述赤氨基酸→卤代酮→卤代醇环氧→:(2S,3S)configu-配给由合成序列来实现的。给出了对所观察到的立体选择性的机械解释。该立体选择性合成方法被用于合成具有预定的手性环氧化物部分的绝对构型的各种短肽基环氧化物。
