room temperature synthesis of a novel serie of 1,4-disubstituted-1,2,3-triazoles 4a-l by employing the (3+2) cycloaddition reaction of pyrimidinones containing alkyne functions with different model azides in the presence of copper sulphate and sodium ascorbate. To obtain the final triazoles, we also synthesized the major precursors 6-amino-5-cyano-1,4-disubstituted-2(1H)-pyrimidinones 3a-r from ethyl
在本文中,我们通过使用含有炔官能团的嘧啶酮与不同模型叠氮化物的 (3+2) 环加成反应,在室温下合成了一系列新型 1,4-二取代-1,2,3-三唑 4a-l。硫酸铜和抗坏血酸钠的存在。为了获得最终的三唑,我们还从 2,2-二氰基乙烯基氨基甲酸乙酯衍生物 2a-c 和各种初级芳香族化合物合成了主要前体 6-amino-5-cyano-1,4-dilocated-2(1H)-pyrimidinones 3a-r含有炔基的胺。三唑以良好到非常好的产率制备。
