Abstract
An efficient, facile, and green synthesis of 4H-pyran and 4H-chromene derivatives in Magnetized Distilled Water (MDW) has been described. In this work, magnetized distilled water was applied as a green-promoting medium for a practical, and environmentally benign three-component reaction of an aldehyde, ethyl acetoacetate/resorcinol, and malononitrile in the presence of potassium carbonate as a catalyst at 70 ºC. This method offers the advantages of simplicity, low costs, high reaction yields, being green, and no need for any organic solvent. Also, the chemical structures of the synthesized new compounds were confirmed using Nuclear Magnetic Resonance (NMR), and InfraRed (IR) spectroscopy analysis.
