Abstract: Gallium(III) halides catalyzed and microwave enhanced three component Biginelli reaction of aldehyde, 1,3-dicarbonyl compounds and urea or thiourea under solvent free conditions to afford 3,4-dihydropyrimidin-2-(1H)-ones in excellent yields is described. The present procedure for the production of dihydropyrimidinones describes the first ever catalytic activity of gallium(III) halides. This improved procedure is fairly simple, facile and environment friendly.
