• Dihydropyrano[c]chromenes
• Biscoumarin
• Malononitrile
• Nano-copper chromite

A clean, efficient and eco-friendly procedure has been developed using nano-copper chromite (nano-CuCr2O4) as catalyst for the synthesis of biscoumarin and dihydropyrano[c]chromene derivatives. This method provides several advantages such as mild reaction conditions, simple work-up procedure and is environment friendly. In addition, water is chosen as a green solvent.
