Efficient synthesis of 3-(4-methyl-3-phenyl- furo [3,2-<i style="">c</i>] quinoline-2-carbonyl)- chromen-2-ones under microwave irradiation

Abstract

A rapid and efficient method for the preparation of 3-(4-methyl-3-phenyl-furo[3,2-<i style="">c</i>]quinoline-2-carbonyl)-chromen-2-ones by the reaction between 3-(2-bromo-acetyl)-chromen-2-ones and (4-hydroxy-2-methyl-quinolin-3-yl)-phenyl-methanones using dimethyl formamide and anhydrous potassium carbonate under microwave irradiation is reported. Microwave assisted reactions have resulted in better yields of the desired products than prepared under conventional conditions. The structures of the compounds are supported by spectral and analytical data.
