Abstract
Abstract Immobilization of chiral thiourea catalyst was studied. The PEG-bound thiourea showed better catalytic activity than those of the carboxypolystyrene HL resin-bound and TentaGel carboxy resin-bound thioureas. In the presence of PEG-bound thiourea, Michael and tandem Michael reactions of trans-β-nitrostyrene proceeded enantioselectively.
