摘要

A new strategy is reported for the C-H/C-H functionalization of 7-azaindazoles at the C6-position through a regioselective oxidative arylation using N-oxide activation. This methodology allowed selective and original access to C6-arylated 7-azaindazoles with different substituted arenes and heteroarenes.
