| Abstract: | A simple and effective method for synthesis of 3,4-dihydropyrimidine-2(1H)-ones from aldehydes,1,3-dicarbonyl compounds and urea using BPy]HSO4 as the catalyst under solvent-free conditions was described.Compared with the classical Biginelli reaction,this method has the advantages good yield,shorter reaction time,reusability of the ionic liquid,and using solvent-free. |
