We designed and synthesized new series of diverse triazoles, isoxazoles, isoxazolines, and aziridines linked 4-methylumbelliferone 1 using intermolecular 1,3-dipolar cycloaddition reactions. Structures of these compounds were established on the basis of (1)H NMR, (13)C NMR, and ESI-HRMS. All prepared compounds were evaluated for their antimicrobial, anticoagulant, and anticholinesterase activities
我们设计和合成了新的系列的三唑,异恶唑,异恶唑啉和氮丙啶使用分子间的1,3-偶极环加成反应连接4-甲基伞形酮1。这些化合物的结构基于(1)H NMR,(13)C NMR和ESI-HRMS确定。评价所有制备的化合物的抗微生物,抗凝血和抗胆碱酯酶活性。有趣的是,在测试的分子中,某些类似物的抗真菌特性显示出比母体4-甲基伞形酮1更好的活性,例如6a和6d。此外,化合物4、5、6和7显示出通过连接基亚甲基向4-甲基伞形酮1中添加的片段具有良好活性的重要性。
