Abstract

Vinly azides are featured as electrophiles, nucleophiles, and radical acceptors in synthetic chemistry and have emerged as rapid and versatile synthons in the preparation of N-heterocyclic systems. Herein, a novel approach to 2-arylindoles via Pd(II)-catalyzed cyclization reaction of anilines with vinyl azides has been achieved, which furnishes the versatile 2-arylindoles with high efficieny and excellent regioselectivity.
