Site-Selective Azaindole Arylation at the Azine and Azole Rings via N-Oxide Activation
摘要:
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.
