| Water is a versatile solvent in many ways, and in this sense performing organic reactions in this medium is now of great interest. The one-pot reaction of ethyl acetoacetate or benzyl acetoacetate, with benzaldehydes and malononitrile to provide some novel 6-amino-4-aryl-5-cyano-2-methyl-4H-pyran-3-carboxylates has been performed over nano MgO with high performance in water as a green solvent at 80 °C. The nanocrystalline MgO catalyst was characterized via X-ray diffraction (XRD), transmission electron microscopy (TEM) and BET analysis. This method offers considerable improvements for the synthesis of 6-amino-4-aryl-5-cyano-2-methyl-4H-pyran-3-carboxylates with concern to the yield of products, facility in operation, and green aspects without using of toxic catalysts and solvents. | ||
