Заглавие : Expanding 1,2,4-triketone toolbox for use as fluorinated building blocks in the synthesis of pyrazoles, pyridazinones and β-diketohydrazones
Место публикации : Journal of fluorine chemistry. - 2022. - Vol. 253. - Ст.109932
Предметные рубрики: ХИМИЧЕСКИЕ НАУКИ
Аннотация: Fluorinated lithium β-diketonates bearing a methyl acetal group behave in the condensation reactions with hydrazines as trielectrophilic building blocks for the preparation of pyrazoles, pyridazinones and β-diketohydrazones. For the first time, solvent-induced regioisomeric and heterocyclic ring size-controlled formation was observed for 1,2,4-triketone analogues. Fluoroalkylated acetyl NH-pyrazoles or substituted 5-RF-pyrazoles were obtained from the acid-catalyzed cyclocondensation of lithium β-diketonates with (aryl)hydrazines in ethanol. In methanol solvent acetyl-containing 3-CF3-pyrazoles were isolated because of inverse nucleophilic attack of arylhydrazines. The use of aprotic acetonitrile in the condensation resulted in regioselective trifluorinated pyridazinones and fluorinated β-diketohydrazones formation via initial acetal fragment interaction with N,N-dinucleophile.

Заглавие : Mechanochemical synthesis of coumarins via Pechmann condensation under solvent-free conditions: an easy access to coumarins and annulated pyrano[2,3-f] and [3,2-f]indoles
Место публикации : Green Chemistry. - 2022. - Vol. 24, № 6. - С. 2429-2437
Предметные рубрики: ХИМИЧЕСКИЕ НАУКИ
Ключевые слова (''Своб.индексиров.''): a green protocol has been developed for the synthesis of simple coumarins and linear pyrano[2,3-f] and [3,2-f]indoles by the reaction of phenol derivatives with β-ketoesters under ball milling at ambient temperature in the presence of methanesulfonic acid as a mild acid catalyst. the significant advantages of this procedure are high yields, scalability, no use of hazardous acids or solvents, shorter reaction time, ambient temperature, low cost, and straightforward purification without column chromatography. this procedure is associated with high ecoscale metrics and a low e-factor. in contrast to traditional pechmann condensation procedures, the mechanochemical protocol leads to the synthesis of pyranoindoles with excellent regioselectivity and high yields.

Заглавие : Abnormal push-pull benzo[4,5]imidazo[1,2-a][1,2,3]triazolo[4,5-e]pyrimidine fluorophores in planarized intramolecular charge transfer (PLICT) state: Synthesis, photophysical studies and theoretical calculations
Место публикации : Dyes and Pigments. - 2022. - Vol. 204. - Ст.110405
Предметные рубрики: ХИМИЧЕСКИЕ НАУКИ
Аннотация: The combination of excellent luminescence with high solvent polarity effect and aggregation induced emission (AIE) is an ideal combination for creating fluorophores/probes with high microenvironmental sensitivity. However, many push-pull chromophores of the D−A type in common intramolecular charge transfer (ICT) state with a significant solvatochromic effect and AIE activity, have poor luminescent properties. Herein, to overcome this problem by using reactions of nucleophilic aromatic hydrogen substitution (SNH), we have designed a series of novel 4-heteroaryl-substituted 2-aryl-2H-benzo[4,5]imidazo[1,2-a][1,2,3]triazolo[4,5-e]pyrimidine fluorophores possessing a planarized intramolecular charge transfer (PLICT) state. All these fluorophores exhibited high luminescence quantum yields (up to 60%) and large Stokes shift values of up to 7459 cm−1. Among them, the fluorophore 4h was found to exhibit the most pronounced positive solvatochromic effect and the probe 4f exhibited the most pronounced aggregation induced emission characteristics. This AIE behavior was further confirmed by means of time-resolved fluorescence lifetime measurements as well as DFT-assisted geometry optimization studies. In the presence of trifluoroacetic acid (TFA) compound 4h exhibited a well-pronounced acidochromism via visible color change from yellow-green to orange which returned to the original yellow-green solution after the addition of triethylamine (TEA). The Stern-Volmer constant for the probe 4h towards TFA was 38 M−1. Finally, for the compounds 4f, g, h theoretical calculations in the ground and excited states in different solvents were carried out to confirm the PLICT process. Based on all above the herein reported PLICT fluorophores 4a-h can be successfully applied as biological probes and optical switches.

Аннотация: New 2-aryl-1,2,3-triazolopyrimidines were designed, synthesized, and characterized. Their optical properties were thoroughly studied in the solid phase, in solution and in a biological environment. Density Functional Theory (DFT) based calculations were performed, including the molecular geometry optimization for both the ground state and the first singlet excited state, the prediction of the UV-Vis absorption and fluorescence spectra, the determination of the molecular electrostatic properties and the solvent effect on the optical properties. The emission intensity was revealed to increase in time upon irradiation. Mass spectrometric research, quantum mechanical calculations, and analysis of literature data suggested a possible photo-transformation pathway through the homolytic cleavage of one of the C–Cl bonds upon irradiation with UV light. The structure of the active intermediate was identified by the series of mass spectrometry experiments and via synthesis of putative transformation products. The kinetic parameters measured in different solvents allowed estimating the rate of these photo-transformations. Biological experiments demonstrated that 2-aryl-1,2,3-triazolopyrimidines penetrate cells and selectively accumulate in the cell membrane and the Golgi complex and endoplasmic reticulum. Their unique properties pave the way for new possible applications of fluorescent 8-azapurines in biology and medicine.

Аннотация: The grafting of silane groups on clay surfaces has been recently investigated in order to fabricate versatile compounds with new potential applications in materials science and ecological engineering. This work explored the influence of variety of solvents with variable polarity on the silanization of halloysite nanoclay (HNT) surface by (3-Glycidyloxy propyl) trimethoxy silane. To this purpose, the functionalization of HNT by 3-Glycidyloxypropyltrimethoxysilane (GOPTMS) has been conducted in Ethanol (polar protic solvent), Tetrahydrofuran (THF) and Acetonitrile (polar aprotic solvents), and Hexane, 1,4-Dioxane and Toluene (non polar solvents). The silane grafted materials were characterized by using several techniques, including Fourier Transform Infrared Spectroscopy (FT-IR), elemental analysis, Scanning Electron Microscopy (SEM), Thermogravimetry (TGA), X-ray Diffraction Analysis (XRD) and Nitrogen adsorption/desorption isotherms. The largest silane loading has been detected for the hybrid nanomaterials prepared in Hexane as a dispersing medium.

Ключевые слова (''Своб.индексиров.''): polyepichlorohydrin--thiourea--synthesis in gel
Аннотация: The conditions for the homogeneous functionalization of polyepichlorohydrin (PECH) with thiourea by the “synthesis in gel” method were experimentally selected. The best solvent for this process is 1,4-dioxane. The reaction mixture visually represents a physical gel in the range of polymer concentrations from 6 to 20%. The composition of the products was characterized by the data of elemental analysis, and specific features of their structure were established using FT-IR spectroscopy and thermogravimetry with the simultaneous IR spectrometric identification of the decomposition products. Thiourea was shown to react with PECH as an ambident nucleophile with the formation of both groups of N-substituted thiourea and fragments of isothiuronium salt. The total degree of functionalization was 90%. The crosslinking of the macromolecules proceeds simultaneously due to which the obtained products with different degrees of functionalization are insoluble in organic solvents. The thiocarbamoylated PECH derivative demonstrates antiselectivity to CuII ions in the sorption of the metal ions of the Irving—Williams series.

Ключевые слова (''Своб.индексиров.''): supported iridium nanoparticles--n-arylhydroxylamine--semi-hydrogenation
Аннотация: Polystyrene stabilized Iridium (Ir@PS) nanoparticles (NPs) as a heterogeneous catalyst have been developed and characterized by IR, UV–Vis, SEM, TEM, EDX and XRD studies. The prepared Ir@PS catalyst showed excellent reactivity for chemo- and regio-selective controlled-hydrogenation of functionalized nitroarenes to corresponding N-arylhydroxylamine using hydrazine hydrate as reducing source and environmentally benign polyethylene glycol (PEG-400) as green solvent. The present methodology was applied for vast substrate scope and found to be compatible with wide range of reducible functional groups. The reaction performed at 85 °C or ambient temperature and completed within 5–80 minutes. The catalyst can easily be filtered out from reaction mixture and reusable.

Место публикации : Современные синтетические методологии для создания лекарственных препаратов и функциональных материалов" (MOSM 2021): V международная конференция: сборник тезисов. - Екатеринбург, 2021. - С. C. PR-186

Аннотация: Nowadays, green chemistry plays an important role for environment. In this context, development of solvent-free ball milling or a grinding approach has attracted considerable interest in organic synthesis.1 Hence, carrying out a reaction under solvent-free conditions and at room temperature is an effective approach to eliminate the use of volatile organic compounds and to obtain the greenness in the process. On the other hands, pyrroles are the small aromatic, nitrogen-containing heterocyclic compounds present in many natural products.2 Pyrrole molecules show important biological relevance such as porphyrins, bile pigments, and coenzymes and are known to exhibit various applications as organic materials.3 In this work, we have presented a highly robust one-pot, four-component cascade cyclization reaction of α-keto aldehydes, anilines, activated alkynes, and aromatic nucleophiles to synthesize a diverse range of pharmaceutically important penta-substituted pyrroles. The reaction proceeded smoothly under ball-milling conditions in presence of iron catalyst.

Ключевые слова (''Своб.индексиров.''): halloysite--n-(2-aminoethyl)-3-aminopropyltrimethoxysilane--sorption of cu(ii)
Аннотация: In order to increase the affinity of the halloysite mineral to 3d-metal ions, its surface was functionalized with N-(2-aminoethyl)-3-aminopropyltrimethoxysilane. A significant influence of the nature of the solvent and silane concentration on the degree of functionalization of halloysite was revealed. According to the data of elemental analysis, FTIR spectroscopy, and thermogravimetry, it was found that the most efficient solvents were tetrahydrofuran and acetonitrile at an equimolar silane to halloysite ratio. The functionalization of halloysite with N-(2-aminoethyl)-3-aminopropylsilyl groups significantly increases the sorption capacity of the material in comparison with both unmodified halloysite and halloysite functionalized with non-chelating 3-aminopropylsilyl groups.

Ключевые слова (''Своб.индексиров.''): ultrasonication--123-triazole--antioxidant activity
Аннотация: The perpetual demand of medicinally significant scaffolds has prompted the synthetic chemists to identify simple and efficient routes for flawless synthesis. A PEG-400:H2O mediated highly versatile, efficacious and selective “Click reaction” of fluorescent organic Probes under ultrasonic irradiation is reported. 1,2,3-Triazole ring has also been revealed to play a crucial role in bioorthogonal methodologies, fragment-based drug design, and biomolecular mimetics. This methodology provides a rapid and efficient approach for the synthesis of 1,4-Disubstituted 1,2,3-triazoles under Copper (I)-Catalyzed Azide-Alkyne [3 + 2] Cycloaddition (CuAAC) conditions in good to excellent yields in less time. This synthetic protocol has been proven to endorse easy work-up under benign reaction conditions. The green solvent system employed has been efficaciously reused several times without any loss of its activity in an aqueous medium. All the title compounds were characterized by using elemental analysis, 1HNMR, 13CNMR, FTIR, and mass spectral data. The newly synthesized compounds were biologically evaluated for their antioxidant activity. The antioxidant activity results demonstrate that all compounds showed good to excellent antioxidant activity, particularly the compounds 5d, 8 b, 8c and 8d exhibited promising radical scavenging activity. Further, photophysical properties of the compounds were accomplished using spectrofluorimeter. By this method, compounds 5c, 5e, 5f, 8a, 8 b, 8c and 8d exhibited fluorescence in the visible region. Molecular docking studies suggested the antioxidant activity of synthesized compounds due to the inhibition of neuronal nitric oxide synthase (HnNOS).

Аннотация: New 3-(1H-imidazol-2-yl)-9H-carbazoles and 6,6′-di(1H-imidazol-2-yl)-9H,9′H-3,3′-bicarbazoles have been prepared, starting from 9-ethyl-9H-carbazole-3-carbaldehyde or 9,9′-diethyl-9H,9′H-[3,3′-bicarbazole]-6,6′-dicarbaldehyde through their reactions with 4-methoxyaniline or 4-fluoroaniline, benzil or 2,2′-thenil [1,2-di(thien-2,2′-yl) glyoxal] and ammonium acetate on reflux in glacial acetic acid. The obtained compounds have been shown to demonstrate an effective fluorescence in the blue spectral region, exhibiting quantum yields in the range of 0.08–0.51, depending on their molecular structure and solvent polarity. The nature of the observed absorption spectra has been elucidated by the TDDFT calculations.
