4‐Amino‐5‐substituted aryl‐3‐mercapto‐1,2,4‐triazoles are versatile synthons for constructing various biologically active heterocycles. Starting from 4‐amino‐5‐substituted aryl‐3‐mercapto‐1,2,4‐triazole 3a–c, a series of new 3,5‐disubstituted‐1,2,4‐triazolo‐[3,4‐b]1,3,4‐thiadiazoles and their 5,6‐dihydrotriazolothiadiazoles were prepared. The structures of all the newly synthesized compounds have been
4-氨基-5-取代芳基-3-巯基-1,2,4-三唑是用于构建各种生物活性杂环的通用合成子。从4-氨基-5-取代芳基-3-巯基-1,2,4-三唑3a-c开始,一系列新的3,5-二取代-1,2,4-三唑并-[3,4-b ]1,3,4-噻二唑及其5,6-二氢三唑噻二唑的制备。所有新合成化合物的结构均已通过元素分析、IR、1H-NMR、13C-NMR和质谱证实。使用纸盘法研究合成化合物的抗菌作用。合成化合物的抗炎和镇痛活性分别通过角叉菜胶诱导的大鼠爪水肿法和埃迪热板法进行评估。
