In this communication, we describe an unprecedented highly enantioselective catalytic conjugateaddition of simple alkyl thiols to alpha,beta-unsaturated N-acylatedoxazolidin-2-ones catalyzed by acid-base bifunctional catalysis. This reaction provides a useful catalytic method for the synthesis of optically active chiral sulfur compounds that are otherwise difficult to prepare by asymmetric catalysis

An efficient approach for synthesizing a series of 2-sulfide carbapenems has been developed using two successive Cu(I)-catalyzed cross-couplings in a single pot. The method involves highly selective intramolecular coupling of lactam and dihaloalkene using 2,2'-bipyridine as a ligand, followed by intermolecular C-S formation in the presence of another ligand (1,10-phenanthroline, PPh 3) and mercaptan
