The synthesizedFe3O4@APTES@isatin-SO3Hmagnetic nanoparticles (MNPs) were characterized using the energy dispersive X-ray spectroscopy (EDX), Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), transmission electron microscopy (TEM), vibrating sample magnetometer (VSM), X-ray diffraction (XRD), and thermogravimetric(TGA) analysis. The Fe3O4@APTES@isatin-SO3HMNPs performed efficient catalytic activity as a magnetically recyclable heterogeneous catalyst for one-pot, condensation reaction of 1,2-dicarbonyl compounds and o-phenylen diamines in ethanol at room temperature to afford quinoxaline derivatives.

Some are endowed with anticoagulant, spasmolitic, diuretic, anticancer and antianaphylactin. On the other hand, some 2-amino-4H-pyrans also can be employed as cognitive enhancers, for the treatment of neurodegenerative disease, including Alzheimer's disease, amyotrophic. In this research, 2-amino-4H-pyran derivatives were synthesized with good yields via a one-pot multicomponent reaction of aldehyde, malononitrile, and dimedone in the presence of DABCO-CuCl as a catalyst in water.
