K2CO3‐mediated [4+1] annulation reactions of N‐acetyl hydrazones with bifunctional amino reagents are described, which provide an environmental‐friendly strategy to construct 1,2,3‐triazoles that does not employ metals, azides, organocatalysis, or oxidants. A series of substituted 1,2,3‐triazole derivatives was prepared with good yields.
描述了N乙酰基hydr与双功能氨基试剂的K 2 CO 3介导的[4 + 1]环化反应,这为构建不使用金属,叠氮化物,有机催化的1,2,3-三唑提供了环境友好的策略或氧化剂。以高收率制备了一系列取代的1,2,3-三唑衍生物。
