From: Dinickel-catalyzed enantioselective reductive addition of imines with vinyl halides

a Biologically active α-chiral amines. b Comparison between classic organometallic addition and reductive addition to imines. c Specific imines have been successfully applied in reductive addition reactions and the challenges of simple N-protected imines. d Dinickel-catalyzed reductive addition of N-Ts imines with vinyl chlorides (this work).
