摘要

An efficient synthesis of dihydropyrimidinones from the aldehyde,1,3-dicarbonyl compound and urea(thiourea)under solvent-free conditions,using fluoroboric acid as the catalyst,is described.Compared with the classical Biginelli reaction conditions,this new protocol has the advantage of high yields,short reaction time and simplicity in the experimental procedure.
