Abstract

A highly enantioselective, organocatalytic Michael addition reaction of unmodified ketones with chalcones has been developed for the first time. The process, catalyzed by (S)-N-(pyrrolidin-2-ylmethyl)-trifluoromethanesulfonamide, affords 1,5-diketones in high yields (73-89%) and with high degrees of enantio- and diastereoselectivity (86-97% ee, > 30:1 dr).
