Abstract

A green, ecofriendly and highly efficient approach for the synthesis of pyrano[2,3-c]pyrazole derivatives through one-pot four-component reactionsin the presence of copper oxide nanoparticles as an efficient reusable catalyst has been developed. The structure of copper oxide nanoparticles was well characterized by a number of techniques. The copper oxide nanocatalyst could be simply recovered via and, upon washing with an organic phase and water, could be recycled at least seven times without a significant decrease in its activity.
