The obtained nIL has been characterized by the fourier transform infrared spectroscopy (FT-IR), energy-dispersive X-ray spectroscopy (EDAX), thermogravimetric analysis (TGA), nuclear magnetic resonance spectroscopy (1H NMR), and field emission scanning electron microscopy (FESEM), techniques. The synthesized nanocatalyst has been used for the three-component one-step synthesis of functionalized spirolactones via the condensation reaction of arylamines, DMAD and isatins. The stereoselective preparation of dispirodihydrofuranyl oxindoles has also been examined successfully through the one-step pseudo-four component condensation of isatins, amines and DMAD, respectively.}, number={4}, journal={Iranian Journal of Catalysis}, publisher={OICC Press}, author={Nikoofar, Kobra and Khani, Shiva}, year={2024}, month={Feb.}, keywords={Nano ionic liquid, DMAD, Spirolactone, Dispirodihydrofuranyl oxindole, Chiral.
