Co-aminobenzamid@Al-SBA-15: a favorable catalyst in synthesis of 2,3-dihydroquinazolin-4(1H)-ones

Abstract

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.

“…To now, several methods have been reported for the one-pot multi-component condensation synthesis of acridine and quinazoline derivatives, 41 employing a wide variety of catalysts such as Fe 3 O 4 /HT-SMTU-Zn II , 42 SBA/AuNP, 43 [Nbdm][OH], 44 Co-aminobenzamid@Al-SBA-15, 45 α-chymotrypsin, 46 Pd(OAc) 2 , 47 KCC-1/Pr-SO 3 H, 48 and CuCl 2 , 49 Co–alanine complex, 50 magnetic praseodymium nanocatalyst, 51 nano-Fe 3 O 4 -DOPA-SnO 2 , 52 MNPs-NPB-SO 3 H, 53 SDS 54 and bentonite. 55 Despite the usefulness of these catalysts, they also have some limitations including high toxicity, use of expensive materials, complex synthetic processes, long reaction times, and sometimes low yields.…”

Green preparation and characterization of AGC-ZM-2022 as a novel mesoporous silica material using palmitic acid as a natural template

“…3a) in the range of 0.9-2, is agreeable with the reported XRD of mesoporous compounds in the literature. [24][25][26][27][28] Due to the high-angle X-ray diffraction (Fig. 3b), there is a wide peak at an angle between 15 and 30, which is attributed to the structure of the mesoporous material.…”

Facile synthesis of pyrazolopyridine pharmaceuticals under mild conditions using an algin-functionalized silica-based magnetic nanocatalyst (Alg@SBA-15/Fe3O4)

“…29,30 Safaei Ghomi et al reported several of supported SBA-15 catalysts. Generally, in these reported works, the SBA-15 mesoporous silica was employed as a support metal species, and a highly dispersed metal catalyst was utilized in different multicomponent reactions, [31][32][33] for example, they prepared functionalized-SBA-15 using a tetradentate ligand to construct a new catalyst. They investigated the efficiency of this catalyst in the synthesis of 2-azapyrrolizidine alkaloids, which have different biological properties.…”
