Nano-Al2O3/CeO2: An efficient and useful catalyst for the synthesis of 2-amino-4H-Pyran derivatives

Benzopyranes and their derivatives are of interest due to their wide range of biological and medicinal properties. In this study, 2-amino-4H-pyran derivatives were obtained through a one-step multi-component reaction of aromatic aldehyde, malononitrile and dimedone in the presence of nano-Al2O3/CeO2 as a catalyst in water with high efficiency and short time.
