An efficient andc onvenient synthesis of pyrrolo[1,2-a]quinoxalines from 1-(2-aminoaryl)pyrrole anda rylacetic acids has been described by using acombination of CuSO 4 as the catalysta nd 2,2'-bipyridyl ast he ligand in the presence of O 2 as an oxidant. The prominentf eatures of this method are the use of readily availablestarting materials, inexpensive catalyst, broad substrate scope and high product yields.
