In this study, ZnAl2O4@ZnO was prepared by the co-precipitation method and characterization was carried out by different analytical techniques such as X-ray diffraction (XRD), energy dispersive X-ray spectroscopy EDAX, scanning electron microscopy SEM, and a Fourier transform infrared spectroscopy (FTIR) technique. The ZnAl2O4@ZnO has been found to be an extremely efficient catalyst for the preparation of β-enamine and β-enaminoester derivatives from β-di-carbonyl compounds and amines. This approach is environmentally friendly and cost-effective, and simple setup and easily reused. Moreover, the developed method can be effectively utilized for the synthesis of β-enamine and β-enaminoester derivatives, to achieve high yields percent in a short time.
