A series of new thiosubstituted 1,3,4-oxadiazole derivatives of coumarin were synthesised by reaction of 7-((5-mercapto-1,3,4-oxadiazol-2-yl)methoxy)-4-methyl-2H-chromen-2-one and α-haloketones by grinding, in solvent-free conditions at room temperature. The reaction was also carried out in ethanol in reflux conditions. Shorter reaction time and better yields were observed in solvent-free conditions
7-((5-巯基-1,3,4-恶二唑-2-基)甲氧基)-4-甲基-2H-色烯反应合成了香豆素的一系列硫代取代的1,3,4-恶二唑衍生物-2-one 和 α-卤代酮在室温下在无溶剂条件下研磨。该反应也在乙醇中在回流条件下进行。在无溶剂条件下观察到更短的反应时间和更好的产率。化合物的结构通过IR、NMR、元素分析和质谱数据表征。评价合成的化合物对不同细菌和真菌菌株的体外抗菌筛选。大多数化合物表现出良好至中等的活性。
