Cobalt(III)-Catalyzed C-H Amidation of 7-Azaindoles with Dioxazolones: Synthesis of 7-Azaindole Amidated Derivatives.

An efficient cobalt-catalyzed C-H amidation of 7-azaindoles was developed by using dioxazolones as the amidating reagent. A wide scope of substituted 7-azaindoles, even N-vinly groups, is suitable for the reaction, generating 7-azaindoles derivatives with potential properties up to 91% yield under straightforward and strong applicable reaction conditions.
