An iodobenzene diacetate (IBD)-mediated simple and green method was determined for the intramolecular oxidative cyclization of 3-aryl-2-pyridiylhydrazones of different aromatic aldehydes in an aqueous medium at room temperature. This efficient strategy provides a route to the synthesis of 3-aryl-1,2,4-triazolo[4,3-a]pyridines in water which eliminates the requirement to use costly and unsafe volatile
确定了一种碘苯二乙酸酯 (IBD) 介导的简单绿色方法,用于在室温下在水性介质中对不同芳香醛的 3-aryl-2-pyridiylhydrazone 进行分子内氧化环化。这种有效的策略提供了一种在水中合成 3-芳基-1,2,4-三唑并 [4,3-a] 吡啶的途径,无需使用昂贵且不安全的挥发性有机溶剂。所有反应仅通过在室温下在水中搅拌反应组分来进行。该协议提供了广泛的底物范围和良好的官能团耐受性。
