ABSTRACT
A domino synthesis of 5,12-dihydroindolo[2,1-b]quinazoline derivatives via copper-catalyzed Ullmann-type intermolecular C-C and intramolecular C-N couplings is reported. Good yields of various 5,12-dihydroindolo[2,1-b]quinazoline derivatives were obtained. Reaction scopes, limitations, and the reaction mechanism are discussed.
