Herein, we report the first facile Cu-free click reaction between alkynyl sulfonium and azide at ambient temperatures in aqueous media. DFT computations indicate that the sulfonium group is the key factor to gaining reactivity by stabilizing LUMO+1 and influencing the charge distribution of the triple bond. Sulfonium alkynes can be easily synthesized and scaled up, and most of them are biocompatible
在这里,我们报告了在环境温度下在水介质中炔基锍和叠氮化物之间的第一个简单的无铜点击反应。DFT 计算表明,锍基团是通过稳定 LUMO+1 并影响三键电荷分布而获得反应性的关键因素。锍炔烃可以很容易地合成和放大,并且大多数是生物相容的。我们准备了候选分子并测试了它们在多个概念验证生物学应用中的用途。
