摘要:
An enantioselective Morita-Baylis-Hillman reaction of maleimides with isatin derivatives has been developed. beta-Isocupreidine catalyzes the formation of enantiomerically enriched 3-substituted 3-hydroxyoxindole derivatives in up to 96% yield and enantioselectivity of over 99% ee can be achieved under mild reaction conditions.
