group at the alkyne group, and the deprotection could be readily achieved with the addition of F–, which renders the reactivity. The substrates were readily synthesized and proven to be stable at the bench. This bioorthogonal fluoride-responsive click reaction was then successfully employed in peptide modification, protein labeling, and cell imaging, suggesting its potential in various applications.
无铜叠氮化物-炔烃环加成广泛应用于众多研究领域。在此,我们报道了一种利用氟化物响应性叠氮化物和炔基吡啶鎓环加成在环境温度下在水介质中进行的简单的无铜点击反应。炔基吡啶鎓的反应性被炔基上的甲硅烷基保护基成功掩蔽,并且通过添加F-可以很容易地实现脱保护,从而赋予反应性。这些底物很容易合成,并被证明在工作台上是稳定的。这种生物正交氟化物响应点击反应随后成功应用于肽修饰、蛋白质标记和细胞成像,表明其在各种应用中的潜力。
