One-Pot Synthesis of Pyrrolo­[1,2‑<i>a</i>]­quinoxaline Derivatives via a Copper-Catalyzed Aerobic Oxidative Domino Reaction

A copper-catalyzed process for the synthesis of pyrrolo­[1,2-<i>a</i>]­quinoxalines from readily available α-amino acids and 1-(2-halophenyl)-1<i>H</i>-pyrroles is described. Different functional groups were well tolerated to give the corresponding products
