Three-component synthesis of cyclic β -aminoesters using CeO2 nanoparticles as an efficient and reusable catalyst

Abstract

CeO2 nanoparticles were used as an efficient catalyst for the preparation of cyclic β -aminoesters by threecomponent 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.
