NiAl2O4 spinel nanocrystals were synthesized as mesoporous catalysts and were fully characterized using Fourier-transform infrared spectroscopy (FT-IR), X-ray diffraction patterns (XRD), scanning electron microscopy (SEM), and Energy-dispersive X-ray spectroscopy (EDS). These nanocrystals catalyzed the synthesis of 2,3-dihydroquinazolin-4(1H)-one derivatives via a one-pot, three-component condensation reaction of aromatic aldehydes, isatoic anhydride, and ammonium acetate or primary aromatic amine under microwave irradiation. By far, the most obvious advantages of the offered process are efficiency and recyclability of the catalyst as well as a significantly shorter reaction time.

An efficient method for the synthesis of a series of 2,3-disubstituted-2,3- dihydroquinazolin-4(1H)-ones is described via one-pot condensation reaction of isatoic anhydride, aryl aldehydes, and primary amines using a Bronsted acidic ionic liquid, [Hmim][N
