[摘要]:A series of novel 4-(2-(4-bromophenyl)-1,2,3-triazol-4-yl)-3,4-dihydropyrimidin-2(1H)-ones /thiones were prepared by condensing 2-(4-bromophenyl)-4-formyl-1,2,3-triazole with 1,3-dicarbonyl compound and urea or thiourea using Mg(NO3)(2) as an efficient and cheap catalyst. The satisfactory results were obtained with excellent yields and short reaction time. |
