title: Regioselective Synthesis of Indolo[1,2-c]quinazolines and 11H-Indolo[3,2-c]quinolines via Copper-Catalyzed Cascade Reactions of 2-(2-Bromoaryl)-1H-indoles with Aldehydes and Aqueous Ammonia.
abstract: Highly selective and convenient synthesis of indolo[1,2-c]quinazolines and 11H-indolo[3,2-c]quinolines through copper-catalyzed one-pot cascade reactions of 2-(2-bromoaryl)-1H-indoles with aldehydes and aqueous ammonia has been achieved. Notably, the regioselectivity was easily controlled by tuning the reaction conditions. Compared with literature methods, the present protocol features easily controlled selectivity, readily available starting materials, good functional group tolerance, and simple operation procedures.
