Abstract

Abstract 9H-α-Carbolines have been prepared via consecutive intermolecular Buchwald– Hartwig reaction and Pd-catalyzed intramolecular direct arylation from commercially available 2, 3-dichloropyridines and substituted anilines. The combination of a high reaction temperature (180 C) and the use of DBU were found to be crucial for the intramolecular direct arylation reactions of the 3-chloro-N-phenylpyridin-2-amines as no reaction was ...
