| Abstract: | Phosphotungstic acid/sulfated zirconia catalyzed one-pot condensation of aryl aldehydes, urea derivatives and β-diketones under microwave irradiation rapidly affords substituted 3,4-dihydropyrimidin-2(1H)-ones in excellent yields and high purity. The low cost catalysts have exhibited remarkable reactivity and reusability for the aforementioned synthesis. |
