A novel series of 1,4-bis(6-(substituted phenyl)-[1,2,4]-triazolo[3,4-b]-1,3,4-thiadiazoles (5a–b) and 4-bis(substituted phenyl)-4-thiazolidinone derivatives (7a–c) have been synthesized from terephthalic dihydrazide (1) through multistep reaction sequence. 1,4-Bis(5-aryl-1,3,4-oxadiazole-2yl) benzene derivatives (2a–f) and bis-substituted terephthalohydrazide (6a–e) were also synthesized from terephthalic
一系列新的1,4-双(6-(取代苯基)-[1,2,4]-三唑[3,4- b ] -1,3,4-噻二唑(5a – b)和4-bis对苯二酰肼(1)通过多步反应序列合成了(取代的苯基)-4-噻唑烷酮衍生物(7a – c)1,4-双(5-芳基-1,3,4-恶二唑-2基)苯衍生物对苯二酰肼(2a – f)和双取代对苯二酰肼(6a – e)也由对苯二酰肼通过与各种芳族酸和醛环化而合成。对苯二酰肼(1从聚对苯二甲酸乙二酯废料中与水合肼反应得到产率为86%的)。筛选所有合成的化合物对各种细菌和真菌菌株的抗菌活性。这些化合物中的几种显示出潜在的抗菌活性。
