A Facile Copper-Catalyzed One-Pot Domino Synthesis of 5,12-Dihydroindolo[2,1-<i>b</i>]quinazolines

A domino synthesis of 5,12-dihydroindolo[2,1-<i>b</i>]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-<i>b</i>]quinazoline derivatives were obtained. Reaction scopes, limitations, and the reaction mechanism are discussed
