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.

oral VEGFR-2 inhibitors that provide sustained ocular retention and efficacy in models of wet-AMD. We disclose herein the synthesis and the biological evaluation of a series of novel core replacements as an expansion of the reported indole based VEGFR-2 inhibitorseries. Addition of heteroatoms to the existing core and/or rearranging the heteroatoms around the 6–5 bicyclic ring structure produced a series

We report a new strategy that translates indoles and related heterocycles into diverse 3D analogs by dearomative hydrocarboxylation. The transformation is highly chemoselective, broad in scope, operationally simple, and readily amenable to high-throughput experimentation (HTE).
