【摘要】 以卤代烃、邻甲基苯胺、氰基乙酸和乙酰氯为原料,经取代、成环、偶联和关环4步反应,用微波法合成了9个[1,2,3]三唑-[4,5-d]嘧啶酮类衍生物（5a～5i）,其中5a～5e, 5g和5i为新化合物,其结构经¹H NMR,¹³C NMR和HR-MS（ESI）表征。更多还原

【Abstract】 Several [1,2,3]triazolo[4,5-d]pyrimidin-one derivatives（5 a～5 i, 5 a～5 e, 5 g and 5 iwere novel compounds） were synthesized by a four-step microwave-assisted reaction of substitution, ring-formation, coupling and ring-closure reaction using halohydrocarbon, o-toluidine, cyanoacetic acid and acetyl chloride as starting materials. The structures were characterized by ¹H NMR, ¹³C NMR and HR-MS（ESI）.更多还原
