These were submitted to palladium-catalyzed cyclization, under different required conditions, to give several differently substituted thieno[3,2-c] or [2,3-b]carbazoles and indolo[3,2-b]benzo[b]thiophenes. This constitutes a novel synthetic route to both tetracyclic systemsengPalladiumAminationOrtho-bromodiarylaminesCyclizationjournal article10.1016/S0040-4020(03)00552-0
