Abstract

Cerium(III) nitrate hexahydrate efficiently catalyzes the three-component Biginelli reaction under solvent-free conditions of an aldehyde, a β-keto ester or β- diketone and urea or thiourea to afford the corresponding 3,4-dihydropyrimidin-2(1H)- ones or –thiones in excellent yields.
Keywords: Dihydropyrimidinones; cerium(III) nitrate; Biginelli reaction; solvent-free synthesis. Dihydropyrimidinones; cerium(III) nitrate; Biginelli reaction; solvent-free synthesis.
