the synthesis of fusedbenzo[c]carbazoles has been achieved in moderate to high yields by the one-potphotochemicalannulation of 3-acyl-2-haloindoles with tetheredstyrenes by photoinduced electron-transfer coupling, electrocyclic reactions, and deacylative aromatization in the presence of pyridine. Fused furo[2,3-c]carbazoles were also synthesized under the same conditions. 5,6-Dihydrobenzo[c]pyrrolo[1
