چکیده	The catalytic application of a novel MgO containing periodic mesoporous organo silica with ionic liquid framework (MgO@PMO-IL) is described as a highly efficient and recoverable catalyst for the synthesis of novel spirooxindole-furan derivatives via the three-component reaction of 1,3-dicarbonyl compounds, N-phenacyl pyridinium salts and isatin derivatives. The MgO@PMO-IL was prepared and charactrized by diffuse reflectance infrared fourier transform spectroscopy (DRIFT), N2 adsorption/desorption analysis, transmission electron microscopy (TEM) and thermogravimetric analysis (TGA). The nanocatalyst was recoverd by simple filtration process and successfully reused seven times without any significant decrease in its efficiency. Spirooxindole-furan derivatives were achieved in high to excellent yields with a simple work-up procedure and short reaction times.
