ABSTRACT:
The present invention presents a method for preparation of S-3,4-dihydroxy butyronitrile expressed by the structural formula (II) ##STR1## characterized by causing R-3-chloro-1,2-propanediol expressed by the structural formula (I) ##STR2## to react with a cyanating agent. According to this invention, optically active 3,4-dihydroxy butyronitrile and 3,4-dihydroxy butyric acid derivatives may be manufactured economically and efficiently.
