The potent nucleophilicity and remarkably low basicity of 1,3,2-diazaphospholenes (DAPs) is exploited in a catalytic, metal-free 1,4-reduction of free alpha,beta-unsaturated carboxylic acids. Notably, the reduction occurs without a prior deprotonation of the carboxylic acid moiety and hence does not consume an additional hydride equivalent. This highlights the excellent nucleophilic character and low basicity of DAP-hydrides. Functional groups such as Cbz group or alkyl halides which can be problematic with classical transition-metal catalysts are well tolerated in the DAP-catalyzed process. Moreover, the transformation is characterized by a low catalyst loading, mild reaction conditions at ambient temperature as well as fast reaction times and high yields. The proof-of-principle for a catalytic enantioselective version is described.

Essential oils and ethanolic extracts of seeds of seven organically and conventionally grown accessions (E1, E2, E3, E4, E5, E6, and E7) of fennel (Foeniculum vulgare Mill.) were examined for their chemical constituents, antioxidant and antibacterial activities. Accession E7 presented the highest essential oil yields of 4.30 +/- 0.45 and 3.24 +/- 0.46%, respectively, for organic and conventional mode. However, E6 noted the lowest ethanolic extract yield in the two modes of cultivation. Gas chromatography/mass spectrometry analysis of the essential oils revealed the presence of nine essential components in all plant materials. (E)-anethole, methyl-chavicol, fenchone, and limonene were highly abundant. A considerable antioxidant effect was shown for all accessions and a significant difference (p < .05) was reported in the mode of cultivation of essential oils and ethanolic extracts. Concerning antibacterial activity, the essential oils showed generally higher antibacterial activity on gram-positive and gram-negative bacteria than ethanolic extracts for organic and conventional fennel seeds. Practical applications Foeniculum vulgare is an aromatic plant widely used nowadays as flavoring as well as food preservative in foods, such as ice cream, meat, and fish dishes. In this context, the chemical composition and biological activities of essential oil and ethanolic extract from fennel seeds cultivated in organic and conventional modes were studied. Fennel seeds extracts presented a richness in polyphenols and flavonoids. In addition, they showed considerable antioxidant activity, while essential oils had a higher antibacterial activity. There is increase demand, nowadays, for such natural and safe products for future applications in the food industries. Product Details of 123-11-5.

The present study evaluates the chemical profiling of the essential oil of a halophyte, L. maritima (LmEO), and its protective potential against CCl4-induced oxidative stress in rats. Forty compounds have been identified in LmEO. The major components are alpha-pinene (3.51%), benzyl alcohol (8.65%), linalool (22.43%), pulegone (3.33%), 1-phenyl butanone (7.33%), globulol (4.32%), gamma-terpinene (6.15%), terpinen-4-ol (4.31%), alpha-terpineol (3.9%), ledol (3.59%), epi-alpha-cadinol (3.05%) and alpha-cadinol (4.91%). In comparison with the CCl4-intoxicated group, LmEO treatment resulted in decreased liver serum marker enzymes, decreased lipid peroxidation and increased antioxidant enzyme levels, with overall further amelioration of oxidative stress. The administration of LmEO to CCl4-treated rats at a dose of 250 mg kg(-1) body weight significantly reduced the toxic effects and the oxidative stress on the liver, thus validating the traditional medicinal claim of this plant. Moreover, the anti-inflammatory activity of LmEO was evaluated in lipopolysaccharide-stimulated murine RAW 264.7 cells. Our oil could modulate the inflammatory mode of the macrophages by causing reduction in iNOS and COX2 enzymes as well as in IL-1 beta, IL-6, and TNF-alpha cytokine levels. These findings suggest that LmEO exerts anti-inflammatory effects by regulating the expression of inflammatory cytokines.

Formula: C7H8O. I found the field of Chemistry very interesting. Saw the article Adsorption Energies of Oxygenated Aromatics and Organics on Rhodium and Platinum in Aqueous Phase published in 2020.0, Reprint Addresses Goldsmith, BR; Singh, N (corresponding author), Univ Michigan, Dept Chem Engn, Ann Arbor, MI 48109 USA.; Goldsmith, BR; Singh, N (corresponding author), Univ Michigan, Catalysis Sci & Technol Inst, Ann Arbor, MI 48109 USA..

Accurately predicting adsorption energies of oxygenated aromatic and organic molecules on metal catalysts in the aqueous phase is challenging despite its relevance to many catalytic reactions such as biomass hydrogenation and hydrodeoxygenation. Here, we report the aqueous-phase adsorption enthalpies and free energies of phenol, benzaldehyde, furfural, benzyl alcohol, and cyclohexanol on polycrystalline Pt and Rh determined via experimental isotherms and density functional theory modeling. The experimental aqueous heats of adsorption for all organics are similar to 50 to 250 kJ mol(-1) lower than calculated gas-phase heats of adsorption, with a larger decrease for Rh compared with that for Pt. Unlike in gas phase, phenol and other aromatic organics adsorb with similar strength on Pt and Rh in aqueous phase. The similar aqueous adsorption strength of phenol and benzaldehyde on Pt and Rh explains their comparable aqueous-phase hydrogenation activities, which are rate-limited by a Langmuir-Hinshelwood surface reaction. A widely used implicit solvation model largely overpredicts the heats of adsorption for all organics compared with experimental measurements. However, accounting for the enthalpic penalty of displacing multiple water molecules upon organic adsorption using a bond-additivity model gives a much closer agreement between experimental measurements and predicted heats of adsorption. This bond-additivity model explains that the similar adsorption strength of organics on Pt and Rh in aqueous phase is due to the stronger adhesion of water to Rh than that on Pt, which offsets the stronger gas-phase organic adsorption energy on Rh. The data reported herein also provides a valuable resource for benchmarking methods for predicting aqueous-phase adsorption energies of CS/C6 organics on metal surfaces.

In this study, Cabernet Sauvignon and Chardonnay musts, and fruit juices from cherry, kiwi, peach, and strawberry were co-fermented with Saccharomyces cerevisiae EC1118 and Torulaspora delbrueckii UMY196 at two different proportions (80:20 (v/v) and 60:40 (v/v)). The most pleasant fruit-based drink was obtained with Cabernet Sauvignon must and kiwi juice in a proportion of 60:40 and fermented with T. delbrueckii. This beverage was produced in higher volume to simulate a scale-up, and the aromatic profile, sensory description, and consumer acceptability were determined. The most powerful odorants of the kiwi-based drink were ethyl octanoate, phenylethanal, ethyl hexanoate, vinyl-guaiacol, benzaldehyde, and nonanal, for which the odor activity values were 21.1, 3.3, 2.6, 2.2, 1.9, and 1.6, respectively. These findings were in accordance with the sensory analysis, since the emerged descriptors were fruity (ethyl octanoate), honey and floral (phenylethanal), apple and peach (ethyl hexanoate), and citrus (nonanal). The consumers judged the kiwi-based drink acceptable (67%) and 39% of them would buy it. The reliable fermentation of a grape must/fruit juice was demonstrated. The kiwi-based drink represents an innovative and pleasant beverage with a positive impact on sustainability as its production can limit the loss of fresh fruits, as well as contribute to the enological field.

A single method with a functionality switching option was developed for the first time for the Pd-catalyzed C-O cross-coupling of aryl bromides and bromo-chalcones with aldoximes. The ligand tBuXPhos (L2) was found to be an effective supporting ligand for the Pd-catalyzed coupling of aldoximes with bromo coupling partners. The functionality switching from oxime ethers to a phenolic or hydroxy group was driven by solvent or temperature. This method offers the products in good to excellent yields in short reaction times.

Protection techniques of functional groups within the structure of organic compounds are important synthetic methods against unwanted attacks from various reagents during synthetic sequences. Acetal and thioacetal groups are well known as protective functional groups in organic reactions. In this study, acetalization of carbonyl compounds with diols and dithiols and methoxymethylation of alcohols with formaldehyde dimethyl acetal (FDMA) have been carried out using sulfamic acid-functionalized magnetic Fe3O4 nanoparticles (SA-MNPs) as a heterogeneous solid acid catalyst. Products were characterized by FT-IR and NMR spectroscopies. The structural and electronic properties of some products were computed by quantum mechanical (QM) methods. Depending on the stereochemistry and electronic properties that were obtained by computational results, we have suggested that hyperconjugation plays a key role in the structural properties of 2-phenyl-1,3-dioxolane derivatives, and also the electron transfer between pi-electrons of the aromatic ring with the 3d orbital of S-atoms influences the 2-phenyl-1,3-dithiane derivatives’ structure.

Essential oils extracted from herbs have been utilized in food and medicine on the account of their increasing physicochemical characteristics. This present study aimed to investigate the phytochemical components, antiinflammatory, cytotoxic, anti-microbial and anti-oxidant activities of essential oils from Pogostemon cablin (P. cablin), Angelica dahurica (A. dahurica) and Myristica fragrans (M. fragrans), all belong to medicine food homology herbs. Approximately 107 components were identified by gas chromatography mass spectrometry (GC-MS) from these essential oils. The main compounds of P. cablin essential oils (PCEOs) were patchouli alcohol (27.72%), alpha-buaiacene (17.94%) and alpha-guaiene (14.15%); in A. dahurica essential oils (ADEOs) were anethole (24.91%) and cinnamaldehyde (18.35%); and in M. fragrans essential oils (MFEOs) were (1S)-(-)-alpha-pinene (23.39%), alpha-terpineol (18.60%) and caryophyllene (10.34%). These essential oils were found to have strong antiinflammatory activities through decreasing the production of cyclooxygenase-2 (COX-2), interleukin-6 (IL-6), nuclear factor-kappa B p65 (P65) and tumor necrosis factor-alpha (TNF-alpha). These essential oils also had significant anti-bacterial activities against both Gram-negative and Gram-positive strains and anti-fungal activities. Moreover, effective anti-oxidant properties of three essential oils were estimated (0.001962%-0.19%). The study also explored the effect of these essential oils on the survival of Brain microglia (BV2) microglial cells (IC50 = 145.50-281.52 mu g/mL). Based on these bioactivities, these essential oils could be used as food additives, fragrances, cosmetics and health products.

Ozonolysis is an oxidative cleavage reaction of alkenes with ozone that is indispensable and has found many applications in organic synthesis. However, dedicated laboratory ozone generators are quite expensive equipment and may not be affordable by many laboratories. Recently, low-cost ozone disinfectors have become more common as a household appliance. Herein, we demonstrate the applicability of a household ozone disinfector, which can produce ozone in the order of 10 mmol/h, as alternative equipment for the laboratory scale ozonolysis of alkenes. The ozonolysis of 14 styrene derivatives bearing electron-donating and electron-withdrawing groups on aromatic rings including those with alpha- and beta-substituents, as well as 8 natural products containing olefinic moieties were investigated. Ozonolysis of these alkenes at millimole scales proceeded to completion within 30-40 minutes and the carbonyl products were obtained in 68% to quantitative yields. Preparative-scale ozonolysis of 4-methoxystyrene (6.17 g, 46 mmol) was also demonstrated. The reaction proceeded smoothly to yield 4-anisaldehyde in 92% yield, which was subsequently converted to p-anisaldehyde dimethyl acetal in 66% yield. This work presents household ozone disinfector as an affordable, compact size, and practical synthetic equipment that does not require extra modification. Thus, the household ozone disinfector offers convenient access to ozonolysis or other reactions involving ozone for low-budget laboratories.
