摘要：

A magnetic ionic liquid supported on γ-Fe2O3 nanocatalyst was synthesized successfully and characterized by Fourier transform infrared spectroscopy, vibrating sample magnetometry, thermogravimetric analysis, differential scanning calorimetry, X-ray diffraction and scanning electron microscopy. The resulting nano-Fe3O4-supported, ionic liquid was an efficient catalyst for preparation of a series of tetracyclic quinazoline compounds by three components reaction of a mixture of isatoic anhydride and amine with ninhydrin in PEG and the desired products were obtained in good to excellent yields. High efficiency, waste-free, mild reaction conditions, effortless magnetic recovery and reusability up to four continuous cycles are the noteworthy features of the currently employed heterogeneous catalytic system.
