The tetracyclic and pentacyclic skeletons of pyrido and quinolinocarbazole alkaloids have been synthesizedviaa unified strategy. The prominent key step involved a Diels-Alder intramolecular cyclization/dehydro-aromatization sequence. From these carbazole-lactam cores, linear syntheses have been developed for ellipticines and calothrixin B.
