Abstract
A novel catalyst based on layered double hydroxides coated with copper nitrate [LDH@(3-chloropropyl)trimethoxysilane@N1,N4-bis(4,6-diamino-1,3,5-triazin-2-yl)benzene-1,4-disulfonamide@Cu] was successfully synthesized. The structure of the new synthesized catalyst was investigated and confirmed using different analytical techniques, such as Fourier-transform infrared spectroscopy (FTIR), energy-scattered X-ray spectroscopy (EDX) mapping, X-ray diffraction (XRD), field-emission scanning electron microscopy (FESEM), and heat gravity/heat derivatization (TGA/DSC). The skilled catalyst proved its efficiency for one-pot three-component synthesis of pyrano[2,3-d]pyrimidine and new dihydropyrazolo[4',3':5,6]pyrano[2,3-d]pyrimidine-dione derivatives. Using this efficient catalyst, products were synthesized with a high yield, in a short time, and under soft and solvent-free conditions. The catalyst can be recovered and reused four times without a significant loss of efficiency.

Abstract
In this study, a Co-MOF was synthesized via a co-precipitation procedure and then used as support for stabilizing Ag ions and producing Co-MOF@Ag2O nanocomposite by microwave irradiation. The characterization of synthesized Co-MOF@Ag2O nanocomposite was performed by using different techniques such as field emission scanning electron microscopy (FE-SEM), energy dispersive X-ray (EDX) analyses, X-ray diffraction (XRD), Thermogravimetric analysis (TGA), Brunauer-Emmett-Teller (BET) and Fourier-transform infrared (FT-IR). The prepared Co-MOF@Ag2O nanocomposite was applied as a heterogeneous nano-catalyst in the synthesis of pyrazolopyranopyrimidines in water at 50 °C via the one-pot multicomponent reaction of ethyl acetoacetate, hydrazine hydrate, aromatic aldehydes and barbituric acid derivatives. Through this straightforward and effective protocol, different tricyclic fused pyrazolopyranopyrimidines were synthesized at high yields, and short reaction times, through an uncomplicated work-up process with no by-product. The Co-MOF@Ag2O nanocomposite has been effectively recycled for four consecutive cycles without appreciable loss in its activity. Cost-effectiveness, no need for column chromatography, mild conditions, catalyst recyclability, and eco-friendly nature make it a promising candidate compared to other methods.

Abstract
The pyranopyrimidine core is a key precursor for medicinal and pharmaceutical industries due to its broader synthetic applications as well as its bioavailability. Among its four possible isomers, we found that 5H-pyrano[2,3-d]pyrimidine scaffolds have a wide range of applicability, and in recent years, they have been intensively investigated, but the development of the main core is found to be more challenging due to its structural existence. In this review article, we cover all of the synthetic pathways that are employed for the development of substituted 4-aryl-octahydropyrano/hexahydrofuro[2,3-d]pyrimidin-2-one (thiones) and 5-aryl-substituted pyrano[2,3-d]pyrimidindione (2-thiones) derivatives through a one-pot multicomponent reaction using diversified hybrid catalysts such as organocatalysts, metal catalysts, ionic liquid catalysts, nanocatalysts, green solvents, catalyst-/solvent-free conditions, and miscellaneous catalysts as well as the mechanism and recyclability of the catalysts. This review mainly focuses on the application of hybrid catalysts (from 1992 to 2022) for the synthesis of 5H-pyrano[2,3-d]pyrimidine scaffolds. This review will definitely attract the world's leading researchers to utilize broader catalytic applications for the development of lead molecules.

Abstract
In the present study, a natural-based heterogeneous catalyst is synthesized. For this purpose, nano-hydroxyapatite (n-HA) is prepared, silica-modified and functionalized with phthalimide. Finally, Ag2+ was immobilized onto n-HA/Si-PA-SC and reduced to Ag nanoparticles by Bellis perennis flowers extract. n-HA/Si-PA-SC@Ag characterized by TGA, FTIR, SEM/EDX, XRD, TEM, BET and ICP-AES techniques. Moreover, metal-ligand interactions in n-HA/Si-PA-SC@Ag complex models were assessed to make a quantitative representation for the immobilization behavior of Ag NPs on the surface of n-HA/Si-PA-SC through quantum chemistry computations. Furthermore, the performance of n-HA/Si-PA-SC@Ag was studied in the nitroarene, methylene blue and congo red reductions. Finally, the recyclability study as well as Ag-leaching verified that, n-HA/Si-PA-SC@Ag was stable and reused-up to four times without losing its activity.

Abstract
Novel Yttrium-metal-organic framework (Y-MOF) was synthesized under optimal conditions of microwave with a power of 20 W, the temperature of 30 degrees of centigrade, and time duration of 10 min. The products were characterized by SEM (morphology and size distribution), TGA (thermal stability), BET technique (surface area), and FTIR (characterization of the related group). The Yttrium-metal-organic framework (Y-MOF) synthesized in this study, after identifying and confirming the structure, was used as an efficient and recyclable catalyst in the synthesis of new pyrazolopyranopyrimidine derivatives. Following the study of the properties and applications of Y-MOF, its anticancer properties on breast cancer cells based on the MTT method were evaluated, and significant results were observed. In addition, the anticancer properties of the pyrazolopyranopyrimidine derivatives were investigated.

Abstract
Barbituric, thiobarbituric acids and their related analogs are reactive synthons for
the synthesis of drugs and biologically, and pharmaceutically active pyrimidines. The present
review aimed to summarize the recent advances in the synthesis of different alkylsubstituted,
fused cycles, spiro-, and binary heterocycles incorporated pyrimidine skeleton
based on barbituric derivatives. In this sequence, the eco-friendly techniques under catalytic
conditions were used for the diverse types of multicomponent reactions under different
conditions for the synthesis of various types of heterocycles. Nano-catalysts are efficient for
the synthesis of these compounds in high yields and effective catalyst reusability. The compounds
are potent antibacterial, cytotoxic, xanthine oxidase inhibitory activities, and attend
as urease inhibitors. The projected mechanisms for the synthesis of pyranopyrimidines, benzochromenopyrimidines,
chromeno-pyranopyrimidines, spiroxyindoles, oxospiro-tricyclic furopyrimidines, pyrimidine-based monoand
bicyclic pyridines were discussed. The potent and diverse biological activities for instance, antioxidant,
antibacterial, cytotoxic, and xanthine oxidase inhibitory activities, as well as urease inhibitors, are specified.

Abstract
SCMNPs@Uridine/Zn is utilized as an environmental-friendly and efficient heterogeneous nanocatalyst for two one-pot four-component condensation reactions, containing hydrazine hydrate, arylaldehyde, ethyl acetoacetate, and barbituric acid to yield tricyclic fused pyrazolopyranopyrimidine derivatives (5a-q), and hydrazine hydrate, arylaldehyde, malononitrile, and dimethyl acetylenedicarboxylate/diethyl acetylenedicarboxylate to yield 3-methyl carboxylate substituted pyrano[2,3-c]pyrazole derivatives (8a-y) under solvent-free conditions with high to excellent yields. The main advantages of this process are easy work-up, short reaction times, no chromatographic purifications, and recyclability of the catalyst for a minimum of six runs without any significant decrease in yields of the products. Also, the prepared catalyst SCMNPs@Uridine/Zn was synthesized and fully characterized by various techniques including Fourier transform infrared spectroscopy (FT-IR), energy dispersive X-ray (EDX), thermogravimetric analysis (TGA), X-ray diffraction (XRD), vibrating sample magnetometer (VSM) and Raman spectroscopy.

Abstract
The solvents used in chemistry are a fundamental element of the environmental performance of processes in corporate and academic laboratories. Their influence on costs, health safety, and nature cannot be neglected. Quantitatively, solvents are the most abundant constituents of chemical transformations; therefore, acting on solvents and replacing standard solvents with safer products can have a great ecological impact. However, not all green solvents are suitable for the wide scope of organic chemistry reactions. A second point to consider is that 50% of pharmaceutical drugs are nitrogen heterocycles compounds. It therefore appeared important to provide an overview of the more ecological methodologies for synthesizing this class of compounds. In this review, all publications since 2000 that describe green reactions leading to the formation of nitrogen heterocycles using safe solvents were considered. We chose water, PEG, and bio-based solvents for their negligible toxicity. The synthesis of five-, six-, and seven-membered aromatic nitrogen heterocycles using green reactions reported in the literature to date is described.

Abstract
:
C-N bond formation reactions are the most important transformations in
(bio)organic chemistry because of the widespread occurrence of amines in pharmaceuticals,
natural products, and biologically active compounds. The Hofmann rearrangement is
a well-known method used for the preparation of primary amines from amides. But, the
traditional version of the Hofmann rearrangement often gave relatively poor yields due to
over-oxidation or due to the poor solubility of some amides in aqueous base, and created
an enormous amount of waste products. Developments over the last two decades, in particular,
have focused on refining both of these factors affecting the reaction. This review
covers both the description of recent advances (2000-2019) in the Hofmann
rearrangements and its applications in the synthesis of heterocycles, natural products and
complex molecules of biological interest. It is revealed that organo-catalytic systems especially hypervalent
iodine-based catalysts have been developed for the green and environmentally friendly conversion of
carboxamides to primary amines and carbamates.

Abstract
An efficient and simple method for the synthesis of chromeno[2,3-d]pyrimidine-diones using SMA/Py/ZnO catalyst has been reported. Zinc oxide nanoparticles were coordinated on a modified poly(styrene-comaleic anhydride) (SMA) support to prevent agglomeration and reduction catalytic activity. The polymer support was easily prepared from the reaction of 3-aminopyridine with SMA. The catalyst was characterized by using various characterization techniques such as FTIR, 1H NMR, SEM, and EDX. The catalytic activity of SMA/Py/ZnO for the synthesis of chromeno[2,3-d]pyrimidine-diones through a multicomponent reaction of 6-amino-1,3-dimethyl uracil, 3,4-methylenedioxyphenol, and an appropriate aryl aldehyde under solvent-free conditions was also studied.

Abstract
Ugi-azide four-component reaction (UA-4CR) as development on Ugi four-component reaction (U-4CR) is the condensation reaction involving an aldehyde, an amine, an isocyanide, and an azide source. Nowadays, UA-4CR has been employed for the efficient and facile production of 1,5-disubstituted-1H-tetrazoles (1,5-DS-1H-Ts). Interestingly, the combination of 1,5-DS-1H-Ts with suitable post-transformations in a tandem manner results in the construction of various classes of heterocyclic compounds bearing 1,5-DS-1H-T moiety. This review aims to provide the application of diverse post-Ugi-azide reaction in the preparation of different N-heterocyclic compounds bearing 1,5-DS-1H-T such as substituted and fused 1,5-DS-1H-Ts.

Abstract
A novel series of N-functionalized 4-aryl-tetrahydrobiquinoline-2,5-(1H,3H)-diones were synthesized in high yields by a one-pot three-component reaction involving 2-chloroquinoline-3-carbaldehydes, Meldrum’s acid, and enaminones (dimedone-based enaminones) in the presence of K2CO3 in CH3CN under reflux condition. To gain a deep insight on the mechanism of the reaction, an extensive series of quantum mechanics calculations in the framework of density functional theory (DFT) were carried out for supporting the suggested reaction pathway.
