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
