5(3)-氨基-3(5)-芳基-1的反应合成2,5,7-三芳基-4,7(6,7)-二氢吡唑并[1,5 - a ]嘧啶-3-腈H-吡唑-4-腈与查尔酮
摘要:
5(3)-氨基-3(5)-芳基-1 H-吡唑-4-腈与1,3-二芳基-2-丙烯-1-酮(查耳酮)在回流DMF中的反应导致2,5 ,7-三芳基-4,7(6,7)-二氢吡唑并[1,5 - a ]嘧啶-3-甲腈。在DMSO溶液中,根据芳基取代基的性质,后者以不同比例存在于两个互变异构的4,7-二氢吡唑并[1,5- a ]嘧啶和6,7-二氢吡唑并[1,5- a ]嘧啶中。在查尔酮 积木。
从碳酸胍与1-和/或3-取代的-5-的反应中获得了许多在1-和/或3-位被取代的4,6-二氨基吡唑并[3,4- d ]嘧啶的新衍生物。氨基-4-氰基吡唑。使用三乙醇胺作为反应介质允许制备某些衍生物,这些衍生物不能从前述的融合方法中获得。还从甲酰胺与相同的5-氨基-4-氰基吡唑的反应中获得了在1-和/或3-位被取代的4-氨基吡唑并[3,4- d ]嘧啶的一些衍生物。筛选了新化合物的体内抗疟活性,但发现它们没有活性。

of new derivatives of 4,6-diaminopyrazolo[3,4-d]pyrimidines substituted in the 1- and/or 3-positions have been obtained from reactions of guanidine carbonate with 1- and/or 3-substituted-5-amino-4-cyanopyrazoles. Use of triethanolamine as a reaction medium permitted preparation of certain derivatives which could not be obtained from the previously described fusion procedure. Some derivatives of 4-aminopyrazolo[3
