A general method for the preparation of substituted pyridazinopyrazolotriazines is reported. 3-Aminopyrazolo[3,4-d]pyridazine was diazotized and coupled with active methylene reagents to afford the tricyclic pyridazino[3',4':3,4]pyrazolo[5,1-c]-1,2,4-triazines with substituents such as methyl, phenyl, ethoxycarbonyl, acetyl or benzoyl, depending on the methylene reagent used. In addition several condensation
报道了制备取代的哒嗪并并吡唑并三嗪的一般方法。将3-氨基吡唑并[3,4-d]哒嗪重氮化并与活性亚甲基试剂偶合,得到三环哒嗪并[3',4':3,4]吡唑并[5,1-c] -1,2,4-取决于所用的亚甲基试剂,具有取代基如甲基,苯基,乙氧羰基,乙酰基或苯甲酰基的三嗪。另外,与肼的几次缩合反应得到相应的酰肼和/或。3与芳族醛的反应得到。筛选产物对五种微生物的抗微生物活性。
