Optically active N-(S-2-acetylthiomethyl-1-oxo-3-phenylpropyl)-glycine benzyl ester useful as an enkephalin inhibitory agent or ACE inhibitory agent can be produced at low cost in an industrial manner, by a method comprising subjecting optically active 2-hydroxymethyl-3-phenylpropionic acid and glycine benzyl ester to condensation to subsequently convert the hydroxyl group into an elimination group, and substituting the elimination group with an acetylthio group.
具有光学活性的N-(S-2-乙酰
硫甲基-1-氧代-3-苯基丙基)-甘
氨酸苄酯可用作
脑啡肽抑制剂或ACE
抑制剂,在工业化生产中可以低成本生产,该方法包括将具有光学活性的2-羟甲基-
3-苯基丙酸和甘
氨酸苄酯进行缩合,随后将羟基基团转化为消除基团,并用乙酰
硫基团替换消除基团。
