A green, one-pot three-component synthesis of 2-amino-4H-pyrans has been represented. The reaction wascatalyzed by CuFe2O4 magnetic nanoparticles as a reusable catalyst under mild conditions. The catalyst can simply beseparated from the reaction mixture with an external magnet and work-up procedure was simple to obtain pyranderivatives in good to excellent yields.
