Rhodium-Catalyzed Asymmetric Arylation of <i>N</i>-Tosyl Ketimines

Abstract

A rhodium-catalyzed addition of sodium tetraarylborates to N-tosyl ketimines is described. Highly efficient asymmetric catalysis has been achieved by employing a chiral diene ligand, constructing chiral amine derivatives possessing α-tetrasubstituted carbon stereocenters with high enantioselectivity.
