An enantioselectiveMichaeladdition of ketones to nitroolefins has been accomplished using a novel chiral amino-naphthalene-derived prolinamides catalyst 1. The desired Michael adducts were obtained in high yields (up to 93%) as well as good diastereoselectivities (>99:1) and enantioselectivities (48%-99% ee).
