An easy efficient method for the synthesis of N-(3,5-dichlorophenyl)-5-alkyl/aryl-3H-1,2,4-triazol-3-one derivatives under microwave irradiation has been developed using the reaction of 3,5-dichloroaniline and ethoxycarbonylhydrazones. This reaction occurs more efficiently and faster than the conventional heating method. We obtained 5-mercapto-1,3,4-oxadiazol derivatives by this method. The newly synthesised compounds have been tested for their antimicrobial activity against Enterobacter cloaceae, Escherichia coli, Klebsiella pneumonie, Pseudomonas aeruginosa, Proteus vulgaris, Salmonella typhimurium, Yersinia pseudotuberculosis, Bacillus subtilis and Staphylococcus aereus.
利用 3,5-二氯苯胺和乙氧羰基肼的反应,开发了一种在微波辐照下合成 N-(3,5-二氯苯基)-5-烷基/芳基-3H-1,2,4-三唑-3-酮衍生物的简便高效方法。这种反应比传统的加热方法更有效、更快速。通过这种方法,我们获得了 5-巯基-1,3,4-恶二唑衍生物。我们对新合成的化合物进行了抗菌活性测试,其抗菌对象包括肠杆菌、大肠杆菌、肺炎克雷伯氏菌、铜绿假单胞菌、普通变形杆菌、鼠伤寒沙门氏菌、假结核耶尔森菌、枯草芽孢杆菌和金黄色葡萄球菌。
