Transition State Analysis of Enantioselective Brønsted Base Catalysis by Chiral Cyclopropenimines
[Image: see text] Experimental (13)C kinetic isotope effects have been used to interrogate the rate-limiting step of the Michael addition of glycinate imines to benzyl acrylate catalyzed by a chiral 2,3-bis(dicyclohexylamino) cyclopropenimine catalyst. The reaction is found to proceed via rate-limit...
