introduction of an endocyclic sulfur atom enables fine‐tuning of the reactivity and stability of thiacycloalkynes for copper‐free click chemistry. The stabilizing effect of the endocyclic sulfur atom allows the use of highly activated seven‐membered rings as reagents for bioorthogonal copper‐free click chemistry.
杂原子有帮助!引入环内硫原子可以微调硫代环炔烃的反应性和稳定性,以用于无铜点击化学。内环硫原子的稳定作用允许使用高度活化的七元环作为生物正交无铜点击化学的试剂。
