N-Acyliminium Cyclization as an Approach for an Asymmetric Synthesis of the Pyrrolo[2,1-a]benzazepine Ring System

Abstract
In this article, we report a facile asymmetric synthesis of the pyrrolo[2,1-a]benzazepine ring system based around a stereoselective N-acyliminium cyclization of a novel chiral lactam template.
