“…Like prior research, 4H-chromenes 4 were produced by mixing BA 1, a simple aromatic aldehyde 2, and malononitrile 3 using mica/Fe 3 O 4 nanocatalyst (Scheme 29). 61 Mica/Fe 3 O 4 nanocomposite was synthesized by analytically pure reagents (Scheme 30). At first, mica was added to boiling H 2 O and stirred magnetically, and then the mixed solution of FeCl 3 Á6H 2 O and FeCl 2 Á4H 2 O was introduced to the mixture.…”

Heterocycles and barbituric acid analogs are particularly used in developing and designing new drugs because of their versatile binding properties for different biotargets. They are present in many natural compounds, vitamins, drugs, and biologically active molecules such as anticancer, antibiotic, antidiabetic, anti‐inflammatory, antidepressant, anti‐HIV, antimicrobial, and insecticidal agents. Using co‐friendly techniques under nanocatalyst conditions drives the synthesis of these bioactive compounds toward green chemistry. This review will investigate the nanocatalysts, including magnetic nanocatalysts, nano metal‐based catalysts, organo‐nanocatalysts, and metal–organic frameworks (MOFs) nanocatalysts employed in the synthesis and design of heterocyclic compounds by barbituric acids from 2017 to 2022.

“…80 From a green and sustainable chemistry perspective, a recent surge of interest has been in designing efficient and cost-effective chemical processes that utilize heterogeneous catalysts to synthesize fine chemicals and pharmaceutical products through multicomponent reactions (MCRs). 81–83 However, the limited catalytic activity of these catalysts remains a significant challenge. Minimizing the particles' size in the heterogeneous catalyst is crucial to overcome this issue.…”

“…Most of the MCRs occur in a straightforward manner with high atom economy and excellent yields. [32][33][34] The Fe 3 O 4 MNPs-supported catalysts have been explored in various one-pot MCRs for the synthesis of biologically significant heterocycles. 35 Thiazoles are a privileged class of nitrogen and sulfur containing heterocycles.…”

A novel silica‐coated magnetite supported boronic acid functionalized nanocatalyst (Fe3O4@SiO2‐Pr‐N=CH‐C6H4B[OH]2) was synthesized using a simple synthetic protocol. The catalyst was fully characterized by using Fourier transform‐infrared (FT‐IR), X‐ray diffraction (XRD), energy dispersive X‐ray (EDX), thermogravimetric analysis‐differential thermal analysis (TGA‐DTA), field emission scanning electron microscopy (FE‐SEM), transmission electron microscopy (TEM) and vibrating sample magnetometry (VSM) techniques. The structural investigations revealed that the catalyst is nano‐sized (average crystallite size 13 nm), spherical, thermally stable, and magnetic in nature having a magnetic saturation of 51.26 emu/g. The catalytic activity of Fe3O4@SiO2‐Pr‐N=CH‐C6H4B(OH)2 was explored in the synthesis of hydrazinyl thiazoles via one‐pot, three‐component reaction of phenacyl halide, thiosemicarbazide and aryl aldehyde in EtOH:H2O (50:50, v/v) at room temperature and it gave above 90% yields of hydrazinyl thiazoles. The catalyst being magnetically separable can be reused six times with the retention of catalytic activity. The present approach offers the advantages of operational simplicity, shorter reaction time, ambient reaction condition, facile separation of catalyst, and higher yields of the products.
