We report the discovery of a new bioorthogonalclick‐and‐release reaction involving iminosydnones and strained alkynes. This transformation leads to two products resulting from the ligation and fragmentation of iminosydnones under physiological conditions. Optimized iminosydnones were successfully used to design innovative cleavable linkers for protein modification, thus opening up new areas in the

Dynamic behavior was shown via (1)H NMR based exchange experiments. Computational deconvolution of (1)H NMR spectra containing the components for more than one of the orthogonal reactions allowed for a semiquantitative analysis of the complex mixtures formed, showing that the reactions proceed independently of each other. Therefore, it is possible to use all fourreactions in onepot in a simultaneous, yet
动态共价反应广泛用于动态组合化学。大多数这些反应在不同的反应条件下进行,当多个反应的组分存在于一个反应容器中时,会表现出交叉反应性。在此,我们报告了四种动态共价反应的研究,这些反应在相同的反应条件下可逆反应并且不表现出任何交叉反应性。通过基于 (1) H NMR 的交换实验显示动态行为。包含多个正交反应组分的 (1) H NMR 谱的计算解卷积允许对形成的复杂混合物进行半定量分析,表明反应彼此独立进行。因此,可以同时但正交的方式在一锅中使用所有四个反应。
