15 using the iron complex salts 13 and 14, followed by oxidative iron-mediated arylamine cyclization, afforded the carbazole derivatives 11 and 12, respectively. These carbazoles were transformed to the corresponding carbazole-1,4quinones 9 and 10 by oxidation with cerium(IV) ammonium nitrate. Finally, regioselective addition of methyllithium at C−1 provided carbazomycin G (7) and carbazomycin H (8)
