CuO-CeO2 nanocomposite catalyzed multicomponent synthesis of benzopyran derivatives

CuO-CeO2 nanocomposite can be used as an efficient catalyst for the multicomponent synthesis of benzopyran derivatives by one-pot condensation ofaromatic aldehdes, dimedone and malononitrile under solvent-free conditions. This procedure provides several advantages such as simple work-up, mild reactionconditions, short reaction times and high yields of the products.
