Abstract

An efficient procedure for the synthesis of fused pyrano[4,3-b]chromene derivatives via three-component condensation reaction of aromatic aldehydes, 2-naphthol and 4-hydroxycoumarin, using CuO@RHA/MCM-41 nanocomposite at room temperature, is described. This nanocomposite consists of CuO nanoparticles and MCM-41 matrix obtained from Rice Husk Ash (RHA). This method provides several advantages, such as simple work-up, eco-friendly procedure and short reaction time along with high yields. All of synthesized compounds were characterized by IR, NMR and Elemental analyses.
