摘要使用纤维素负载的碘化亚铜纳米粒子,通过苯甲酸丙-2-炔-1-基酯与芳香族叠氮化物之间的环加成反应,在水中进行酯连接的1,4-二取代的1,2,3-三唑的合成。通过诸如FT-IR,1 H NMR,13 C NMR光谱和质谱技术的各种光谱技术确认了所有合成的三唑的结构。体外评估了合成的三唑的抗菌和抗氧化活性。结果表明,大多数合成的化合物具有中等至良好的活性。通过X射线单晶衍射进一步确认了一种三唑的结构。 图形摘要

A combination of the oxidative N‐heterocyclic carbene catalysis and click chemistry has been explored for the direct, one‐potsynthesis of 1,2,3‐triazole derivatives from aromaticaldehydes. This procedure was found to be very efficient and a variety of 1,2,3‐triazole derivatives could be accessed through their corresponding propargyl esters in moderate‐to‐good yields under mild conditions.
