Abstract

ABSTRACT:In the present work various conventional methods and microwave method for synthesis of substituted quinolone reported. Substituted anilines were taken as a starting material and reacted with ethyl acetoacetate in presence of catalytic amount of acid and cyclized by various cyclisation agents that give the title compounds which differ in its color intensity, reaction time as well in %yield. Based on results we obtain, it has been concluded that microwave method for synthesis of substituted quinolone is more convenient in terms of reaction time and use of solvent.
