Unsymmetrical bisazides containing chelating and non-chelating azido groups undergo chemoselective three-component copper(I)-catalyzed azide-alkyne conjugation reactions with two different alkyne molecules. In conjunction with the reactivity gap between aromatic and aliphatic alkynes, a bistriazole molecule can be generated with an excellent regioselectivity by mixing two alkynes and a bisazide in a single reaction container. This method is applicable in aqueous solutions at neutral pH, which may lend utilities in bioconjugation applications.
含有螯合和非螯合偶氮基团的不对称双偶联物可通过选择性化学反应,在两种不同的炔烃分子中,与三元铜(I)催化偶联反应发生反应。结合芳香族和脂肪族炔烃之间的反应性差异,通过在单个反应容器中混合两种炔烃和一个双偶氮基团,可以生成一个具有极佳区域选择性的双三唑分子。这种方法适用于中性pH值的水溶液中,可能在生物偶联应用中发挥作用。
