We report herein the efficiency of quaternary ammonium salts as co-catalysts in organocatalyticMichaelreactions involving iminiumactivation of alpha,beta-unsaturated aldehydes. The enantioselective formal benzylation of these substrates has been optimized and used to rationalize the role of the ammonium salts in these processes.
