以芳醛、4-羟基香豆素和3-甲基-1-苯基-5-氨基吡唑为原料,用少量冰醋酸作溶剂,三组分一锅法合成一系列吡唑并[4’,5’:3,2]吡啶并[5,6-c]香豆素衍生物,该反应产率高(79%～94%)、操作简单、后处理方便.产物的结构经红外光谱、核磁共振氢谱、元素分析及单晶X射线分析证实.
A series of pyrazolo [4] triazoles were synthesized by one-pot method from aromatic aldehydes, 4-hydroxycoumarins and 3-methyl-1-phenyl-5-aminopyrazoles using a small amount of glacial acetic acid as the solvent ’, 5’: 3,2] pyrido [5,6-c] coumarin derivatives, the reaction yield is high (79% ~ 94%), easy to operate, easy to post-processing the structure of the product by infrared spectroscopy , 1H NMR, elemental analysis and single crystal X-ray analysis.
