title: Site-selective azaindole arylation at the azine and azole rings via N-oxide activation.
abstract: Subjection of N-methyl 6- and 7-azaindole N-oxides to a Pd(OAc)2/DavePhos catalyst system enables regioselective direct arylation of the azine ring. Following deoxygenation, 7-azaindole substrates undergo an additional regioselective azole direct arylation event in good yield.
