The novel hybrid Co-aminobenzamid@Al-SBA-15 was synthesized as a modified mesoporous catalyst. To achieve this aim, the obtained materials were investigated by various techniques including Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), N 2 adsorption–desorption, field emission scanning electron microscopy (FE-SEM) and transmission electron microscopy (TEM) to examine the functional groups, crystallinity, surface area, morphology, particle size distribution and amounts of functional groups, respectively. Co-aminobenzamid@Al-SBA-15 exhibits excellent catalytic activity for the synthesis of 2,3-dihydroquinazolin-4(1 H )-ones under mild reaction conditions. The heterogeneous catalyst showed good recyclability and can be reused for ten consecutive cycles without significant loss of its catalytic activity.

The novel hybrid catalyst Cu@IA‐SBA‐15 was synthesized by anchoring isatoic anhydride on amino‐functionalized SBA‐15. The synthesized process pursued by grafting of Cu(II) to catch desired product. 2D‐hexagonally ordered mesoporous of bidentate ligand characterized by X‐ray diffraction spectroscopy (XRD), N2 adsorption analysis, Field emission scanning electron microscopy (FESEM), Transmission electron microscopy (TEM), fourier‐transform infrared spectroscopy (FTIR), Energy‐dispersive X‐ray spectroscopy (EDX), and Thermogravimetric and differential thermal analysis (TGA‐DTA). The activity of catalyst has been scrutinized in Biginelli‐Like reaction through the environmentally benign conditions by using ultrasound irradiation and green solvents. The methodology offers remarkable development by easy production of hybrid catalyst Cu@IA‐SBA‐15 in regard to solve the problem of using harsh catalysts. It also demonstrates to be impressive and environmentally friendly in term of low reaction times and high yields.

We used a novel hybrid catalyst in chemo-, regio-, and diastereoselective multi-component reactions (MCR).
