Cu(II) ions were precipitated on nanofiberous magnesium silicate support using hydroxide solution. The texture and characterization of the obtained solids have been investigated by physical methods including XRD, SEM, BET, EDS, XPS, and FT-IR. The catalysts showed medium surface area, highly distributed Cu(II) oxide on the sepiolite fibers. In the liquid-phase oxidation of benzyl alcohol at low temperatures, CuO serves as an active component for the selective production of benzaldehyde. The catalytic activity of the prepared CuO/sepiolite was associated with the dispersion and amount of CuO loading, location and oxidation states of active sites, preparation routes, and reaction variables.

Mesoporous, highly temperature resistant, magnetically separable, bimetallic, and organic-based photoluminescent nanocatalyst has been prepared. Chitosan can act efficiently as a support material for preparing nanocatalysts. Hybrid ceria, that is, iron-doped-cerium oxide (Fe@CeO2), was prepared via coprecipitation method. Chitosan-iron-doped-ceria nanocomposite was prepared and kept in a solution of NiCl2 to adsorb Ni2+ ions, which were then reduced with NaBH4 to accumulate nickel nanoparticles. The characterization of nanocatalyst was performed using different techniques such as X-ray diffraction (XRD), field emission scanning electron microscopy (FE-SEM), high-resolution transmission electron microscope (HR-TEM), energy dispersive X-ray spectra (EDX), Brunauer-Emmett-Teller (BET), X-ray photoelectron spectroscopy (XPS), and thermogravimetric analysis (TGA) analysis. The catalyst was found to have a very small size about 2-3 nm and having a large surface area of about 121 m(2) g(-1), which was stable up to 800 degrees C. It was also found to be photoluminescent. The catalyst thus prepared is useful for the reduction of nitroarenes, which is a toxic compound that is often found as a pollutant in the environment, to anilines, key intermediates for the fine chemical, agrochemical, and pharmaceutical industries. Also, nanocatalyst was used for the synthesis of various substituted tetrahydrobenzo[b]pyrans, which is an essential structural component in various natural products, in good to excellent yields.

Extracts from Different Plant Tissues in 2020.0, Cited 46.0. The Name is Benzyl Alcohol. Through research, I have a further understanding and discovery of 100-51-6.

Indian mustard or Brassica juncea (B. juncea) is an oilseed plant used in many types of food (as mustard or IV range salad). It also has non-food uses (e.g., as green manure), and is a good model for phytoremediation of metals and pesticides. In recent years, it gained special attention due to its biological compounds and potential beneficial effects on human health. In this study, different tissues, namely leaves, stems, roots, and flowers of three accessions of B. juncea: ISCI 99 (Sample A), ISCI Top (Sample B), and Broad-leaf (Sample C) were analyzed by HPLC-PDA/ESI-MS/MS. Most polyphenols identified were bound to sugars and phenolic acids. Among the three cultivars, Sample A flowers turned were the richest ones, and the most abundant bioactive identified was represented by Isorhamnetin 3,7-diglucoside (683.62 mu g/100 mg dry weight (DW) in Sample A, 433.65 mu g/100 mg DW in Sample B, and 644.43 mu g/100 mg DW in Sample C). In addition, the most complex samples, viz. leaves were analyzed by GC-FID/MS. The major volatile constituents of B. juncea L. leaves extract in the three cultivars were benzenepropanenitrile (34.94% in Sample B, 8.16% in Sample A, 6.24% in Sample C), followed by benzofuranone (8.54% in Sample A, 6.32% in Sample C, 3.64% in Sample B), and phytone (3.77% in Sample B, 2.85% in Sample A, 1.01% in Sample C). The overall evaluation of different tissues from three B. juncea accessions, through chemical analysis of the volatile and non-volatile compounds, can be advantageously taken into consideration for future use as dietary supplements and nutraceuticals in food matrices.

Electronic cigarettes (e-cigarettes) have become popular alternatives to traditional tobacco. Despite this, a comprehensive evaluation of their long-term effects and safety for the consumers and the environment is missing. To contribute to filling this gap, headspace solid-phase microextraction combined with gas chromatography-mass spectrometry (HS-SPME/GC-MS) was employed to establish and compare the volatile fingerprints of traditional tobacco and e-cigarettes. The analysis of traditional tobacco included two popular brands and different parts of the cigarette (solid tobacco, cigarette smoke, cigarette paper and filter). Regarding the e-cigarettes, two e-liquids, with and without nicotine, their main constituents (e-bases) and corresponding vapours, obtained under default vaping (power) conditions, were analysed. A total of 80 volatile organic compounds (VOCs) were identified in traditional tobacco, of which 14 carbonyl compounds, 9 benzene derivatives, 9 ethyl esters and 9 hydrocarbons. Slight differences in the volatile profile of cigarette paper and filter between the two brands were also detected, showing that exogenous components of tobacco influence the flavour and harmfulness perceived by the smokers. In turn, 92 VOCs were identified in e-cigarettes, including 31 ethyl esters, 18 alcohols and 10 hydrocarbons. No VOCs with potentially toxic or harmful effects were identified in the vapour of Do It Yourself (DIY) liquids and Premium samples. Therefore, taking into consideration the volatile compositions obtained for smoking and vaping procedures under normal conditions of operation and using certified e-liquid mixtures, the e-cigarettes analysed seemed to constitute a valid and less harmful alternative to traditional tobacco for smokers, secondhand smokers and the environment.

The Pot, Atom, and Step Economy (PASE) approach is based on the Pot economy principle and unites it with the Atom and Step Economy strategies; it ensures high efficiency, simplicity and low waste formation. The PASE approach is widely used in multicomponent chemistry. This approach was adopted for the synthesis of previously unknown hydroxyquinolinone substituted chromeno[2,3-b]pyridines via reaction of salicylaldehydes, malononitrile dimer and hydroxyquinolinone. It was shown that an ethanol-pyridine combination is more beneficial than other inorganic or organic catalysts. Quantum chemical studies showed that chromeno[2,3-b]pyridines has potential for corrosion inhibition. Real time H-1 NMR monitoring was used for the investigation of reaction mechanism and 2-((2H-chromen-3-yl)methylene)malononitrile was defined as a key intermediate in the reaction.

Androgen-deprivation therapy (ADT) is only a palliative measure, and prostate cancer invariably recurs in a lethal, castration-resistant form (CRPC). Prostate cancer resists ADT by metabolizing weak, adrenal androgens to growth-promoting 5 alpha-dihydrotestosterone (DHT), the preferred ligand for the androgen receptor (AR). Developing small-molecule inhibitors for the final steps in androgen metabolic pathways that utilize 17-oxidoreductases required probes that possess fluorescent groups at C-3 and intact, naturally occurring functionality at C-17. Application of the Pictet-Spengler condensation to substituted 4-(2-aminoethyl)coumarins and 5 alpha-androstane-3-ones furnished spirocyclic, fluorescent androgens at the desired C-3 position. Condensations required the presence of activating C-7 amino orN,N-dialkylamino groups in the 4-(2-aminoethyl)coumarin component of these condensation reactions. Successful Pictet-Spengler condensation, for example, of DHT with 9-(2-aminoethyl)-2,3,6,7-tetrahydro-1H,5H,11H-pyrano[2,3-f]pyrido[3,2,1-ij]quinolin-11-one led to a spirocyclic androgen, (3R,5S,10S,13S,17S)-17-hydroxy-10,13-dimethyl-1,2,2 ‘,3 ‘,4,5,6,7,8,8 ‘,9,9 ‘,10,11,12,12 ‘,13,13 ‘,14,15,16,17-docosahydro-7 ‘ H,11 ‘ H-spiro-[cyclopenta[a]phenanthrene-3,4 ‘-pyrido[3,2,1-ij]pyrido[4 ‘,3 ‘:4,5]pyrano[2,3-f]quinolin]-5 ‘(1 ‘ H)-one. Computational modeling supported the surrogacy of the C-3 fluorescent DHT analog as a tool to study 17-oxidoreductases for intracrine, androgen metabolism.

A Fe-III-triflate complex, bearing a bis-thioether-di-phenolate [OSSO]-type ligand, was discovered to promote the ring-opening of glycidol with alcohols under mild reaction conditions (0.05 mol % catalyst and 80 degrees C). The reaction proceeded with high activity (initial turnover frequency of 1680 h(-1) for EtOH) and selectivity (>95 %) toward the formation of twelve monoalkyl glyceryl ethers (MAGEs) in a regioselective fashion (84-96 % yield of the non-symmetric regioisomer). This synthetic approach allows the conversion of a glycerol-derived platform molecule (i.e., glycidol) to high-value-added products by using an Earth-crust abundant metal-based catalyst.

Xanthene dyes, such as fluorescein and rhodamine, have played crucial rules in biological sciences especially covalent attachment of these organic compounds to biomolecules. 3-O-methylfluorescein and 3,6-O-dimethylfluorescein were synthesized and purified using a facile procedure. 3,6-O-dimethylfluorescein, which lacks fluorescence, was treated with sodium hydroxide and sulfuric acid solutions, giving rise to yellow and green fluorescent compounds, respectively. In both basic and acidic conditions, donor-acceptor structures were formed. The reaction of 3,6-O-dimethylfluorescein with acids, in a reversible manner, emitted green fluorescence, whereas its reaction with hydroxide ion, irreversibly shifted the fluorescence to the yellow region. Using MS spectrometry, the product identity was determined as a xanthylium ion derivative. Stokes shift and quantum yield for xanthylium ion were measured. Various nucleophiles were examined for studying the mechanism of the xanthylium ion in aqueous solutions; the results confirmed that hydroxide ion was mediatory for the emission of the fluorescence. In addition, 3-O-methyl-5(6)-carboxyfluorescein and 3,6-O-dimethyl-5(6)-carboxyfluorescein were synthesized that can potentially be used in bioorthogonal reactions for labeling proteins. The synthesized products were used in covalent attachment to bovine serum albumin (BSA) and their unique fluorescences were detected.
