Synthesis of Pyrido[1,2-a]benzimidazoles through a Copper-Catalyzed Cascade C-N Coupling Process

A simple and efficient method for the preparation ofpyrido[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 %). A simple and efficient method for th...
