摘 要:Binaphthyl sulfonimides have been developed to catalyze the asymmetric Michael addition of ketone to alky- lidene malonates, affording the corresponding Michael products in good to high yields (up to 98%) with good to excellent diastereoselectivity (up to 99 ; 1 dr) and enantioselectivity (up to 92% ee) under mild conditions using environmentally benign water as the solvent.Binaphthyl sulfonimides have been developed to catalyze the asymmetric Michael addition of ketone to alky- lidene malonates, affording the corresponding Michael products in good to high yields (up to 98%) with good to excellent diastereoselectivity (up to 99 ; 1 dr) and enantioselectivity (up to 92% ee) under mild conditions using environmentally benign water as the solvent.
