Abstract

PURPOSE: A-racemic mixture of 2-thienylsulfinylacetic acid is subjected to selective crystallization from its supersaturated solution in an aqueous medium and devided into optically active derivatives with no use of an optically resolving agent, which is useful as an intermediate of cephalosporin.
