Organocatalyzed Michael addition reactions of 2-(arylthio)cyclobutanones with trans-β-nitrostyrenes have been carried out using a bifunctional thiourea-primary amine catalyst, providing diastereoisomerically and enantiomerically enriched 2-alkyl-2-(arylthio)cyclobutanones having two contiguous stereocenters of which one is a chiral quaternary center. The absolute configuration of these novel adducts
