Three-component synthesis of cyclic $\beta $-aminoesters using CeO$_{2}$ nanoparticles as an efficient and reusable catalyst

CeO2 nanoparticles were used as an efficient catalyst for the preparation of cyclic beta-aminoesters by three-component reaction between primary amines, ethyl acetoacetate, and chalcones in ethanol. Atom economy, low catalyst loading, reusable catalyst, and high yields of products are some of the important features of this protocol.
