Abstract
Facile palladium-catalyzed cyclizations of arylaminoquinones giving biologi cally important carbazoloquinones in high yields have, been performed with oxygen as the single oxidant. By a slight modification of the catalyst, dip henylamine, diphenyl ether, and related compounds can be cyclized. The syst em could also be used in intermolecular couplings between naphthoquinones a nd benzene or naphthalene.
