Résumé Thirteen novel indole derivatives were efficiently synthesized through ultrasound irradiation by using 4-amino-5-(1H-indol-3-yl)-4H-[1,2,4]triazole-3-thiol (8) and 2-mercapto-5-substituted-1,3,4-oxadiazoles (5a–m). Compared with conventional and microwave methods, yields increased to 82–93%, and reaction times decreased to 15–35 min. The structures of these novel compounds were characterized by spectral data and elemental analysis. Two out of the synthesized compounds (10f and 10l) exhibited excellent activity against Staphylococcus aureus and Escherichia coli, and thus warrant further research.

摘要 通过超声辐照,以4-氨基-5-(1H-吲哚-3-基)-4H-[1,2,4]三唑-3-硫醇(8)和2-巯基-5-取代的-1,3,4-噁二唑(5a–m)为原料,高效合成了十三种新型吲哚衍生物。与传统方法和微波方法相比,产率提高到82–93%,反应时间缩短到15–35分钟。这些新化合物的结构通过光谱数据和元素分析得到表征。合成的化合物中有两种(10f和10l)对金黄色葡萄球菌和大肠杆菌显示出优异的活性,因此值得进一步研究。
