We reported a strategy for the synthesis of fused heterocyclic compounds benzo[e]indolo[1,2-a]pyrrolo/ pyrido[2,1-c][1,4]diazepine-3,9-diones via an AgSbF6/gold-complex catalyzed one-pot cascade trans- formation. The strategy is tolerant of a broad range of substrates and affords a series of intriguing fused diazepinedione heterocycles.
