Two efficient and practical approaches are reported for the synthesis of β- and γ-carboline derivatives from 3,4-dibromopyridine as a common starting material. The β-carbolines were prepared by site-selective Pd-catalyzed C–C coupling with o-bromophenylboronic acid and subsequent cyclization by double C–N coupling with amines. γ-Carbolines were prepared from the same starting material by C–N coupling

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
