Site-selective azaindole arylation at the azine and azole rings via N-oxide activation
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.
