Synthesis of Carbolines by Photostimulated Cyclization of Anilinohalopyridines
摘要:
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.

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.
