The application of Fe۳O۴-L-proline in the synthesis of ۲-amino-۴H-chromenes andremoving of heavy metal from waste water at ambient temperature under ultrasonicirradiation

Fe۳O۴-L-proline as an effective and recyclable magnetic nanocatalyst was prepared and characterizedusing different methods. Then, it was efficiently used for the promotion of the one-pot synthesis of ۲-amino-۴Hchromenesvia one-pot three-component reaction of the dimedone, malononitrile, and aryl aldehydes underultrasonic irradiation in ethanol as solvent
