A rapid, efficient and environment-friendly protocol for the synthesis of naphthopyranes has been developed by one-pot condensation of 2-naphthol, various aromatic aldehydes and benzoylacetone or 1,3-diphenyl-1,3-propandione in the presence of Cu(OTf)2 as catalyst under ultrasonic irradiation. The present approach offers the advantages of clean reaction, simple methodology, short reaction time, high yield and economic availability of the catalyst.
