Abstract	A novel magnetically immobilized polyethyleneimine (PEI) fabricated by covalently anchoring on MCM-41 (MCM-41@PEI) was prepared. The synthesized catalyst was characterized by Fourier transform infrared (FTIR), thermogravimetric analysis (TGA), X-ray powder diffraction (XRD), scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The immobilized PEI was shown to be an efficient heterogeneous catalyst for the synthesis of spiro-oxindole and benzopyranes derivatives via multi-component reaction (MCR), in ethylene glycol as a green solvent. No leaching problem was observed after several runs, while the catalyst can be recovered and reused without loss of reactivity under the described reaction conditions.
