A one-potsynthesis of α-carbolines via a palladium-catalyzed aryl amination followed by intramoleculararylation is described. 2,3-Dichloro- and 2,3-dibromopyridines have been shown to react with readily available anilines to obtain various substituted α-carbolines in moderate to excellent yields.

A methodology for the synthesis of α- and β-carbolines from fluoropyridines and 2-haloanilines is reported. This procedure consists of a four-step directed ortho-lithiation, zincation, Negishi cross-coupling, and intramolecular nucleophilic aromatic substitution, providing access to a diverse set of functionalized carbolines. While the procedure is applicable to batch conditions, the generation of
