Silica sulfuric acid, a heterogeneous reagent, has been found to be an efficient catalyst for the synthesis of -enaminones and -enaminoesters under microwave irradiation in a microwave reactor within 2 min. The experimental procedure is simple and environment-friendly, and results in excellent yields of the products. Further, the catalyst is recyclable, and the reaction is 60 times faster than the reaction at room temperature. GRAPHICAL ABSTRACT[image omitted].

Nanocrystalline Copper(II) Oxide–Catalyzed One-Pot Synthesis of Imidazo[1,2-<i>a</i>]quinoline and Quinolino[1,2-<i>a</i>]quinazoline Derivatives via a Three-Component Condensation
A simple, efficient, and practical procedure for the synthesis of imidazo[1,2-a]quinoline and quinolino[1,2-a]quinazoline derivatives using CuO nanoparticles as a novel catalyst in excellent yields is described. The catalyst can be recovered conveniently and reused at least four times without any loss of activity.
