摘要
A new enantioselective approach to obtain a tetrasubstituted chiral center at the C3 position of oxindoles via a catalytic asymmetric Morita-Baylis-Hillman reaction has been demonstrated. This reaction provides 3-substituted 3-hydroxy-2-oxindoles in good to excellent yields and ee values, which could be facilely transformed to pharmaceutically more interesting compounds.
