/camphor with nanospheres structure was developed for utilization as the heterogeneous Bronsted acid in chemical transformation. The synthesis and characterization of camphor supported on magnetic nanoparticle using FTIR, XRD and SEM-EDX are described. The three-component and one-pot synthesis of 2-amino-4H-chromenes by condensing aromatic aldehyde, malononitrile/ethyl cyanoacetate and barbituric acid/thiobarbituric in water solvent, in the presence of catalytic amount of nanoparticle Fe

/camphor under microwave irradiation was investigated. The products obtained were characterized by FTIR, UV/Vis spectrophotometer, and mass analysis. The compounds were investigated for their antibacterial activity against Escherichia coli, Bacillus cereus, Salmonella enterica ser. Typhimurium, Staphylococcus aureus, and Pseudomonas aeruginosa. Also, the antioxidant properties of the compounds were analysed using DPPH method. This method corresponding a facile synthesis of 2-amino-4H-chromenes derivatives produced shorter reaction times, good yields and selectivity. The supported catalyst could be separated from the reaction product using an external magnet and proved to be simple, efficient and environmentally friendly.
