A class of mono-protected 3-amino-2- hydroxypyridine (MPAHP) ligands that enable the meta- C-H arylation of anilines, phenols, phenylacetic acids, and biologically relevant heterocyclic compounds using norbornene as a transient mediator is disclosed. The applicability of this meta-arylation methodology in the pharmaceutical industry is illustrated for heteroaryl substrates and heteroaryl iodide coupling partners, a feat made possible by using the MPAHP ligand. The enabling nature of MPAHP ligands to achieve other meta-C-H functionalization processes is also illustrated by the development of a meta-C-H amination reaction and a meta-C-H alkynylation reaction.
一种单保护的3-氨基-2-羟基吡啶(MPAHP)配体类别,能够利用去环戊烯作为瞬时介质,实现苯胺、酚、苯乙酸和生物相关杂环化合物的间位C-H芳基化。该间位芳基化方法在制药行业中的适用性通过对杂环底物和杂环碘化合物的示例进行说明,这一成就得益于使用MPAHP配体。MPAHP配体的启用性质还通过开发间位C-H氨化反应和间位C-H炔基化反应来展示其实现其他间位C-H官能化过程的能力。
