Abstract A one-pot procedure for the synthesis of novel 1,2,3-triazole derivatives (5a–5l) in good yields (63 to 77%) using different sulfonic acids and 4-(prop-2-yn-1-yl)thiomorpholine 1,1-dioxide through the in situ generated sulfonyl azides was developed. The structures of the newly synthesized compounds were confirmed by 1H NMR, 13C NMR, mass spectrometry, and elemental analysis. The newly synthesized
摘要 一锅法使用不同的磺酸和4-(prop-2-yn-1-yl)合成新的1,2,3-三唑衍生物(5a-5l),产率高(63%至77%)通过原位生成的磺酰叠氮化物开发了硫代吗啉1,1-二氧化物。通过1 H NMR,13 C NMR,质谱和元素分析确认了新合成的化合物的结构。通过DPPH法从供氢或自由基清除能力方面筛选了新合成的化合物的体外抗菌活性和自由基清除活性。其中,化合物N发现-(4-((4-((1,1-dioxidothiomorpholino)甲基)-1H-1,2,3-三唑-1-基磺酰基)苯基)乙酰胺(5l)与标准药物。
