N-Arylation of azaindoles in LiCl-mediated catalytic CuI reactions
摘要:
N-Arylation of 5- and 7-azaindoles was achieved in LiCl-mediated catalytic Cul reactions at 120 degrees C with moderate to high yields. N-Arylation can be performed with various arylhalides, such as phenyl, pyridine, quinotine, thiophen, and thiazole moieties. (c) 2007 Published by Elsevier Ltd.

An efficient and convenient bimetallic MnF2/CuI catalyst in combination with trans-1,2-diaminocyclohexane has been developed for the cross-coupling of nitrogen heterocycles with aryl halides in water at moderate temperature. A variety of nitrogen nucleophiles including pyrazole, 7-azaindole, indazole, indole, pyrrole and imidazole afforded the corresponding products in moderate to good yields (up to

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.
