Abstract
Abstract We report herein, the usage of N , O -bis(trimethylsilyl)acetamide (BSA) and dicyclohexyl carbodimide (DCC) as two new catalysts for three component condensation of an aldehyde, ethyl acetoacetate and urea/thiourea under solvent free conditions at 100 °C to afford the corresponding 3,4-dihydropyrimidine-2-(1 H )-ones/thiones (DHPMs) in good to excellent yields. A comparative study of these two catalysts was made and presented.
