Asymmetric Aza-Diels-Alder Reaction Catalyzed by Boron Reagent: Effect of Biphenol and Binaphthol Ligand

Abstract
An asymmetric aza-Diels-Alder reaction of chiral imine catalyzed by an in situ generated achiral and chiral boron complex is described. The method is successful with both aromatic and aliphatic aldimines and affords products of up to 99% de.
