Abstract	N-Heterocyclic carbene (NHC)-catalyzed diastereoselective synthesis of multisubstituted sulfenylated indanes has been developed. In the presence of 1 mol% NHC, various thiols underwent the sulfa-Michael-Michael cascade reaction with benzenedi(enones) efficiently to form the carbon-sulfur bond and construct sulfenylated indanes in good to excellent yields with high diastereoselectivity. In addition, the NHC-catalyzed sulfa-Michael-aldol cascade reaction between o-formyl chalcone and thiols has also been demonstrated to afford sulfenylated indanes with a free hydroxyl group in moderate yields and good diastereoselectivity.
