Enantioselective N‐Heterocyclic Carbene Catalyzed Aza‐Benzoin Reaction of Enals with Activated Ketimines

Abstract

α-Amino ketones, which are versatile building blocks for organic synthesis, were obtained with the title reaction. A free hydroxy group on the NHC catalyst was found to be crucial for the reaction, and the possible competing reaction through a homoenolate or enolate was not observed with this catalyst (see scheme).
