microwave-assisted green chemical synthesis of condensed 2-substituted-pyrimidin-4(3H)-ones 3, 4, and 5 involving the condensation of a variety of nitriles with o-aminoesters of thiophene , benzene , dimethoxybenzene and quinazolinone in the presence of catalytic amount of HCl alone or with the Lewis acid AlCl3 under solvent-free conditions, is described for the first time. This novel and clean one-pot methodology
冷凝2-取代的嘧啶-4(3所述的快速微波辅助绿色化学合成ħ) -酮3,4,和5涉及缩合的各种腈和ö噻吩-aminoesters苯 ,二甲氧基苯 和喹唑啉酮 首次描述了在无溶剂条件下单独在催化量的HCl或与路易斯酸的AlCl 3存在下的催化量。这种新颖,干净的一锅法方法具有反应时间短,后处理简便的特点,可用于生成缩合嘧啶杂环的各种文库。J.杂环化学。(2009)
