Synthesis of 1,4-dihydropyridines by three-component condensation reaction of aldehyde, 1,3-dicarbonyl compounds, and ammonium acetate have been found to be efficiently catalyzed by uranyl nitrate hexahydrate [UO2(NO3)2 · 6H2O] at room temperature under ultrasound irradiation. This novel synthetic method offers the advantages of high yields, short reaction times, simplicity, and easy workup compared
通过醛,1,3-二羰基化合物和乙酸铵的三组分缩合反应合成1,4-二氢吡啶被发现可被六水合硝酸铀酰[UO 2(NO 3)2 · 6H 2 O]有效地催化。在室温下超声照射下。与文献中报道的常规方法相比,这种新颖的合成方法具有高收率,反应时间短,简单且易于后处理的优点。
