An efficient and simplified protocol for NaHSO 4 /SiO 2 catalyzed solvent-free synthesis of β-enaminone and 2-methyl-quinolin-4( 1H)-onederivatives under microwave irradiation is described. A series of functionalized derivatives have been synthesized in shorter reaction times with moderate to good yields. The use of milder catalyst in non-conventional method offers significant advantages over conventional
