The 5‐heterofunctionalized triazoles are important scaffolds in bioactive compounds, but current click reactions (CuAAC) cannot produce these core structures. A copper(I)‐catalyzed interrupted click reaction to access diverse 5‐functionalized triazoles is reported. Various 5‐amino‐, thio‐, and selenotriazoles were readily assembled in one step in high yields. The reaction proceeds under mild conditions
5杂功能化的三唑是生物活性化合物中的重要支架,但是当前的点击反应(CuAAC)无法产生这些核心结构。据报道,铜(I)催化的间断点击反应可访问各种5官能化的三唑。多种5-氨基,硫代和硒代三唑易于一步一步组装,高收率。反应在温和条件下进行,具有完全的区域选择性。它还具有广泛的底物范围和良好的官能团相容性。
