“…As a result of our great interest in preparation of heterocyclic compounds by applying heterogeneous catalysts [25, 26], herein we wish to report an efficient procedure to synthesize 2,3-dihydroquinazolin-4(1 H )-one derivatives through a three-component one-pot condensation of isatoic anhydride, aromatic aldehyde and primary amines/or ammonium acetate using Co-aminobenzamid@Al-SBA-15 as catalyst (Scheme 1).…”

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.

“…As a result of our great interest in preparation of heterocyclic compounds by applying heterogeneous catalysts, herein we wish to report an efficient procedure to synthesize spiro[indoline‐3,2′‐quinazoline] derivatives through a three‐component one‐pot condensation of isatoic anhydride, isatins and primary amines/or ammonium acetate using V‐N‐C@Al‐SBA‐15 as catalyst (Scheme ). Beforehand, the reaction of isatoic anhydride, isatin and aniline was picked out as a model reaction.…”

Heterogeneous nanoscale catalyst was successfully synthesized via anchoring of V‐bis(2‐aminobenzamide) complex on the Al‐SBA‐15. This modified mesoporous was identified by several characterization techniques, such as X‐ray diffraction, field emission‐scanning electron microscopy, Fourier transform‐infrared, Brunauer–Emmett–Teller and transmission electron microscopy. V‐Bis(2‐aminobenzamide)@Al‐SBA‐15 was found to be an efficient heterogeneous catalyst for the rapid and desirable synthesis of various spirooxindole dihydroquinazolinones derivatives. In addition, the heterogeneous nanocatalyst was chemically stabilized in organic and aqueous solutions as well as can be expeditiously reused for at least seven cycles without a significant loss in catalytic activity.

“…In 2014 Safaei‐Ghomi and co‐authors investigated the use of CuI nanoparticles as a catalyst for this reaction. [ 333 ] It was shown that even 3 mol‐% of CuI nanoparticles with 3 mol‐% of 1,10‐phenanthroline as a ligand is more efficient than 15 mol‐% of bulk CuI with 15 mol‐% of 1,10‐phenanthroline. KOH was used as a base.…”
