An efficient and convenient synthesis of pyrrolo[1,2‐a]quinoxalines from 1‐(2‐aminoaryl)pyrrole and arylacetic acids has been described by using a combination of CuSO₄ as the catalyst and 2,2′‐bipyridyl as the ligand in the presence of O₂ as an oxidant. The prominent features of this method are the use of readily available starting materials, inexpensive catalyst, broad substrate scope and high product yields.
