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

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