Optically active N-[(S)-2-(acetylthiomethyl)-1-oxo-3-phenylpropyl]-glycine esters derivatives of formula (IV)(wherein R1 represents hydrogen, an optionally substituted amino acid side chain or a protected amino acid chain; R2 represents and optionally substituted linear of branched C1 to C18 alkyl group, or an optionally substituted benzyl group; and * denotes an optionally active carbon atom) useful as enkephalin inhibitory agents of ACE inhibitory agents can be produced at low cost in an industrial manner, by subjecting optically active 2-hydroxymethyl-3-phenylpropionic acid and glycine esters to condensation, subsequently converting the hydroxyl group into an elimination group, and substituting the elimination group with an acetylthio group.
公式(IV)的光学活性N-[(S)-2-(乙酰硫甲基)-1-氧代-3-苯基丙基]-甘氨酸酯衍生物(其中R1代表氢原子,一个可选择性取代的氨基酸侧链或保护的氨基酸链;R2代表一个可选择性取代的直链或支链C1到C18烷基或一个可选择性取代的苯甲基;*代表一个可选择性活性的碳原子),可用作ACE抑制剂或enkephalin抑制剂。这些衍生物可以在工业上以低成本生产,方法是将光学活性的2-羟甲基-3-苯基丙酸和甘氨酸酯经过缩合,随后将羟基转化为消除基,然后用乙酰硫基取代消除基。
