Abstract

With the cooperation of Cram's phenonium ion, a novel cascade reaction was illustrated to construct pyrrolo [1, 2-a] quinolines as a sole diastereoisomer in good to excellent yields. Preliminary mechanistic studies revealed that the γ-lactam ring and electron-rich arene are important driving forces for ring contraction.
