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.

triethylamine is described. The pyridin-4-yl α-substituted acetamide products were obtained in moderate to high yields. The presented rearrangement reaction, in which the presumed N-acylated intermediate reacts intramolecularly via nucleophilic aromatic substitution, results in a formal two-carbon insertion.
