The catalytic asymmetric phospha-Michael reaction of dialkyl phosphine oxides with beta,beta-disubstituted alpha,beta-unsaturated carbonyl compounds was achieved. The products bearing tetrasubstituted carbon stereocenters were obtained in high yields with excellent enantioselectivities (up to >99% ee).
