Synthesis Of Pyrido[1,2-A]Benzimidazoles Through A Copper-Catalyzed Cascade C-N Coupling Process

A simple and efficient method for the preparation of pyrido[1,2-a]benzimidazoles by a copper-catalyzed inter- and intramolecular C-N coupling cascade process was designed and carried out, and the products were obtained in moderate to excellent yields (up to 93%).
