We report the late-stage functionalization of multisubstituted pyridines and diazines at the position α to nitrogen. By this process, a series of functional groups and substituents bound to the ring through nitrogen, oxygen, sulfur, or carbon are installed. This functionalization is accomplished by a combination of fluorination and nucleophilic aromatic substitution of the installed fluoride. A diverse
我们报告了多取代吡啶和二嗪在氮的 α 位的后期功能化。通过这个过程,安装了一系列通过氮、氧、硫或碳与环结合的官能团和取代基。这种官能化是通过氟化和安装的氟化物的亲核芳族取代的组合来完成的。由于 2-氟杂芳烃的亲核芳香取代 (SNAr) 显示出温和的反应条件,因此可以安装多种功能。替代率与竞争过程率的评估提供了规划此功能化序列的框架。这个过程通过一系列具有药用价值的化合物的修饰来说明,
