An efficient and simplified protocol for NaHSO4/SiO2 catalyzed solvent-free synthesis of β-enaminone and 2-methylquinolin-4(1H)- one derivatives 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 methods, such as higher selectivities, simplicity, solvent-free reaction and non-environmental polluting conditions.

Reaction of enaminoketones (1), derived from dimedone, with pyruvic acid gave the lactams (2) and (3).Compounds (2) were dehydrated to (3) with acetic anhydride.In the case of (2j), two diastereoisomers were isolated due to restricted rotation of the N-ar
