Abstract:
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.

Claim (Index 21):
The substituted 3-amino-2-hydroxypyridine ligand according to  claim 20 , wherein m and p are both zero, and at least one of R 16 , R 17  and R 18  is other than hydrido.
