and 4-aminoantipyrine (1) by three steps. The treatment of compound 5 with CS2 afforded the conversion of hydrazide function into 5-mercapto-1,3,4-oxadiazole ring leading to the formation of 7. Then, 7 gave the product containing triazolotriazine moiety (9) by the reaction with hydrazine hydrate. The synthesis of the compounds incorporating the 1,3,4-thiadiazole (10a–c), 1,2,4-triazole (11a–c) or 1,3-thiazole
乙酰肼衍生物含有安替比林和三唑核(5获得从乙基肼衍生物(起始)2)和4-氨基安替比(1)通过三个步骤。用CS 2处理化合物5使酰肼官能团转化成5-巯基-1,3,4-恶二唑环,导致7的形成。然后,通过与水合肼反应,7得到含有三唑三嗪部分的产物(9)。包含1,3,4-噻二唑(10a – c),1,2,4-三唑(11a – c)的化合物的合成)或1,3-噻唑(12,13)作为核第三杂环用的化合物的酸性或碱性处理来进行图6A - Ç这是从反应得到的5具有多个异硫氰酸酯,或通过缩合6A与两个不同的苯甲酰溴。 抗菌活性研究表明,除3 – 5外,所有化合物均显示出良好的活性。
