CuO NPs catalyzed synthesis of quinolines, pyridines, and pyrroles via dehydrogenative coupling strategy

Copper oxide nanoparticles catalyzed efficient synthesis of quinolines, pyridines, and pyrroles via alcohol dehydrogenative coupling strategy are reported. Employing this catalytic system, various functionalized quinolines, pyridines, and pyrroles were synthesized efficiently from different amino alcohols with a diverse range of ketones. A number of control experiments were performed to shed light on the mechanism. This catalyst was recycled up to 6th run and notably, no significant loss was observed in its catalytic activity.
