Pyrimidoindolones are an important structural motif found in many natural products and essential to the pharmaceutical agrochemical industry. Direct synthesis of 3,4-unsubstituted pyrimidoindolones is not easily accessible. Here we report a rhodium(III)-catalyzed C-H/N-H activation annulation approach for obtaining from N-carbamoylindoles vinylene carbonate. The reaction occurs at room temperature does require any external oxidants. A diverse spectrum indoles were demonstrated be viable substrates capable producing desired high yields. In addition, scope has been expanded include pyrrole substrate. Furthermore, detailed mechanistic studies have performed delineate working mode reaction.
