摘要

Abstract An efficient one-pot synthesis of sterically hindered aromatic tertiary amines through Lewis acid induced intermolecular Schmidt reaction of benzylic azides is described. In the presence of EtAlCl 2, benzylic azide underwent a smooth Schmidt reaction to give the corresponding iminium ion, which, upon reduction with NaBH 4 in situ, afforded the tertiary amine. The effects of substituents on the aromatic ring and the steric effects of the alkyl ...
