A direct synthesis of several 1,2-disubstituted 4-, 5-, 6-, and 7-azaindoles from available amino-o-halopyridines is described. This procedure involves a palladium-catalyzed N-arylation followed by a Sonogashira reaction and subsequent cyclization in a one-pot manner, exhibiting a wide scope and compatibility with electron-withdrawing and electron-donating groups. The strategy represents an advancement

cascade C–N cross-coupling/Heckreaction of alkenyl bromides with amino-o-bromopyridines is described for a straightforward synthesis of substituted 4-, 5-, 6-, and 7-azaindoles using a Pd2(dba)3/XPhos/t-BuONa system. This procedure consists of the first cascade C–N cross-coupling/Heck approach toward all four azaindole isomers from available aminopyridines. The scope of the reaction was investigated and

Ultrasound assisted one-pot and direct access to 1,2-diaryl substituted azaindole derivatives has been achieved via the sequential N-arylation followed by coupling-cyclization under Pd/C-Cu catalysis. The methodology involved initial C-N bond forming reaction (step 1) between an appropriate o-bromo substituted amino pyridine and iodoarene followed by C-C and C-N bond formation (step 2) between the

A general synthetic route to prepare all four carboline regioisomers by photo stimulated cyclization of anilinohalopyridines is described. The methodology affords various substituted carbolines in good to excellent yields. In the case of alpha-carbolines, the S(RN)1 methodology complements previously reported palladium-catalyzed cyclization approaches.
