Chiral oxiranes are converted into chiral aziridines with overall retention of configuration by means of sulfur chemistry.The key step of this procedure is the transformation of the organosulfur intermediates, i.e., the replacement of a hydroxy group boun

In chiral alcohols bearing a phenylthio group at the β carbon atom, the hydroxy group is replaced by nitriles through the anchimeric assistance of the phenylthio group to afford chiral amides with retention of configuration.This stereospecific Ritter-type
