Abstract

A metal-free hydrosilylation of N-sulfonyl ketimines under the FLP catalysis has been realized to give optically active amines in high yields with up to 73% ee. Significantly, a chiral borane-catalyzed asymmetric hydrosilylation of vicinal diimines was also achieved, affording the desired cis-1,2-diamines with 12–70% ee’s.
