PROCESS FOR MANUFACTURING AN OPTICALLY ACTIVE (S)-3,4-EPOXYBUTYRIC ACID SALT

摘要

This invention relates to a process for manufacturing an optically active (S )- 3,4-epoxybutyric acid salt and more particularly, to a method for manufactui ng (S)-3,4-epoxybutyric acid salt expressed by formula (1), wherein an opticall y active (S)-3-hydroxybutyrolactone is employed to undergo an economical ring- opening reaction and epoxydation so that its chiral center is maintained in an original form. In said formula, R1 represents alkali metal atom, alkaline earth metal atom, alkylamine group or quarternary amine group.
