Novel fused 1H-benzo[f]chromen-indole derivatives were synthesized regioselectivly in good to high yields by triethyl amine catalyzed condensation of 3-cyanoacetylindoles, beta-naphthol and aryl aldehydes in methanol under ultrasounic irradiations and conventional conditions. The easy work-up of the products, rapidity, and mild reaction conditions are notable features of this protocol. The antibacterial activity of the selected products was examined. Some products showed promising activities. (C) 2012 Elsevier Ltd. All rights reserved.
