A Ziegler-Natta catalyst system (TiCl 4 -MgCl 2 /magnesium chloride-methanol adduct) was efficiently found to catalyze the three component Biginelli reaction of an aldehyde, ␀-keto ester, and urea or thiourea under solvent free conditions to afford the corresponding 3,4-dihydropyrimidin-2-(1H)-ones
