ASYMMETRIC REDUCTION OF S-ALKYL-S-ARYL-N-p-TOSYLSULFILIMINES WITH L(–)CYSTEINE

Abstract

Partial reduction of racemic mixture of S-alkyl-S-aryl-p-tosyl sulfilimines with L(–)cysteine affords optically active recovered sulfilimine. In the case of S-methyl-S-p-tolyl-N-p-tosylsuifilimine the absolute configuration and the optical yield were determined.
