This invention relates to a process for manufacturing an optically active (S)-3,4-epoxybutyric acid salt and more particularly, to a method for manufacturing (S)-3,4-epoxybutyric acid salt expressed by the following formula 1, wherein an optically active (S)-3-hydroxybutyrolactone is employed to undergo an economical ring-opening reaction and epoxvdation so that its chiral center is maintained in an original form,
Wherein, R1 represents alkali metal atom, alkaline earth metal atom, alkylamine group or quarternary amine group.
本发明涉及一种制造光学活性(S)-3,4-环氧丁酸盐的方法,更具体地,涉及一种制造由以下式子1表示的(S)-3,4-环氧丁酸盐的方法,其中使用光学活性(S)-3-羟基丁酸内酯进行经济环开反应和环氧化反应,以保持其手性中心的原始形式。其中,R1代表碱金属原子、碱土金属原子、烷基胺基团或季铵基团。
