An efficient, 1,4-diazabicyclo[2.2.2]octane(DABCO)-mediated decarboxylative cyclization of isatoic anhydrides with active methylene groups namely aroyl/heteroaroyl/alkoylacetonitriles undermicrowave condition was developed for the synthesis of substituted 4-quinolones. This method utilizes commercially available substrates, occurs under mild conditions, short reaction time, good to excellent yields
