synthesized by condensing 4-amino-3-[4-methylthiobenzyl]-4H-1,2,4-triazole-5-thiol (5) with substituted aryl furoic acids/aromatic acids in the presence of POCl3. The triazole (5) was obtained by the fusion of 4-methylthiophenyl acetic acid (4) with thiocarbohydrazide. The structures of newly synthesized compounds are characterized by elemental analysis, IR, 1H NMR and mass spectroscopic studies and were screened
通过将4-氨基-3- [4-甲基硫代苄基] -4 H -1,2,4-三唑-5-硫醇(5)与取代基缩合,合成了一系列取代的三唑并二唑(6a – j和7a – j)。POCl 3存在下的芳基糠酸/芳酸。通过使4-甲基硫代苯基乙酸(4)与硫代碳酰肼熔融,得到三唑(5)。 通过元素分析,IR,1 H NMR和质谱研究对新合成化合物的结构进行表征,并筛选其抗菌活性。初步结果表明,某些化合物显示出有希望的抗菌活性。
