Name: Benzyl Alcohol. I found the field of Food Science & Technology very interesting. Saw the article Volatile profile of fermented sausages with commercial probiotic strains and fructooligosaccharides published in 2019.0, Reprint Addresses Barretto, ACD (corresponding author), UNESP Sao Paulo State Univ, Dept Food Technol & Engn, St Cristovao Colombo 2265, BR-15054000 Sao Jose Do Rio Preto, SP, Brazil..

The effect of the partial substitution of pork back fat by fructooligosaccharides (FOS) and the probiotic strains Lactobacillus paracasei and Lactobacillus rhmanosus on the generation of volatile organic compounds in fermented sausages was investigated. The results obtained showed that these factors significantly affected the total content of organic volatile compounds (7484, 8114, 8372 and 10,737 AU x 10(4)/g for FOS.GG, CON, FOS.BGP1 and FOS samples, respectively). A total of 59 volatile components, mainly hydrocarbons, ketones and esters were isolated. The reduction of fat content by including FOS in the formulation results in positive effects and a greater stability of the volatile profile of the fermented sausages, increasing ester compounds and reducing the undesirable notes of hexanal (probiotic samples showed values < 2 AU x 10(4)/g). Moreover, there was a symbiotic effect when the aforementioned prebiotic fiber was combined with probiotic Lactobacillus strains.

Coordination of 1,4-disubstituted 1,2,3-triazoles L-1 and L-2 with [(p-cymene)RuCl2](2) followed by dehydrochlorination in the presence of a base resulted in the formation of complexes 1 and 2, respectively. Both were tested for the transfer hydrogenation of aldehydes and ketones in air using ecologically benign and cheap ethanol as the hydrogen source in the presence of a catalytic amount of a base. Air-stable complex 1 was proved to be an active catalyst for the transfer hydrogenation of a wide variety of aromatic and aliphatic aldehydes and ketones bearing various functionalities. Catalyst 1 was also effective for the transfer hydrogenation of carbonyls using the simplest primary alcohol, methanol, under aerobic conditions. Under the present catalytic protocol, labile or reducible functionalities such as nitro, cyano, and ester groups were tolerated. Good selectivity was also observed for acyclic alpha,beta-unsaturated carbonyls. However, this catalytic protocol was not selective for 2-cyclohexen-1-one as both alkene and keto moieties were reduced. The transfer hydrogenations are believed to proceed via a ruthenium-hydride intermediate. Finally, transfer hydrogenation of acetophenone using isopropanol as a commonly used hydrogen source was also performed and the sustainable and green credentials of these catalytic protocols utilizing methanol, ethanol, and isopropanol were compared with the help of the CHEM21 green metrics toolkit.

A large number (63) of well-defined nitroxide radicals, all phenol-based TEMPO and PROXYL esters, were synthesized using different strategies based on well-established Steglich esterifications. All of these radicals can be used as spin probes (SPs) and spin labels (SLs) for electron paramagnetic resonance (EPR) spectroscopy of supramolecular systems. Depending on the nature of the functional group(s) on each SP/SL, the synthesized nitroxide radicals serve as polyphilic molecular toolbox for the EPR-spectroscopic detection and characterization of specific types of interactions, e. g. pi-pi interactions, sulfur-sulfur interactions, hydrogen bonding, electrostatic and dipole-dipole interactions, and van der Waals and hydrophobic interactions, in the presence of the selected supramolecular systems of interest (e. g. proteins, peptides). For each synthesized SP/SL the water solubility was gravimetrically determined for use in aqueous solution at pH 7.

Prompted by the observation that the regioselectivities of phenolate reactions (C versus O attack) are opposite to the predictions by the principle of hard and soft acids and bases, we performed a comprehensive experimental and computational investigation of phenolate reactivities. Rate and equilibrium constants for the reactions of various phenolate ions with benzhydrylium ions (Aryl(2)CH(+)) and structurally related quinone methides have been determined photometrically in polar aprotic solvents. Quantum chemical calculations at the SMD(MeCN)/M06-2X/6-31+G(d,p) level confirmed that O attack is generally favored under kinetically controlled conditions, whereas C attack is favored under thermodynamically controlled conditions. Exceptions are diffusion limited reactions with strong electrophiles, which give mixtures of products arising from O and C attack, as well as reactions with metal alkoxides in nonpolar solvents, where oxygen attack is blocked by strong ion pairing. The Lewis basicity (LB) and nucleophilicity (N, s(N)) parameters of phenolates determined in this work can be used to predict whether their reactions with electrophiles are kinetically or thermodynamically controlled and whether the rates are activation-or diffusion-limited. Comparison of the measured rate constants for the reactions of phenolates with carbocations with the Gibbs energies for single electron transfer manifests that these reactions proceed via polar mechanisms.

A modest, competent and green synthetic procedure for novel coumarinyl-1,3,4-oxadiazolyl-2mercaptobenzoxazoles 8i-t has been reported. Analysis of the docked (PDB ID: 5IKR; A-Chain) poses of the compounds illustrated that they adopt identical conformations to the extremely selective COX-2 inhibitor. The biological outcomes as well as computational study suggested that the compounds originated to have elevated resemblance towards COX-2 enzyme than COX-1. The compounds 8i, 8l, 8q, 8r, 8s and 8t emerged as most potent and selective COX-2 inhibitors in contrast with Mefenamic acid. The selectivity index of 8l, 8n and 8r was respectively found to be 33.95, 20.25 and 24.98 which manifested their high selectivity against COX-2. Interestingly, the compounds which were active as COX-2 inhibitors were also active as antioxidant agents.

A series of twenty new chloropyrazine conjugated benzothiazepines (22-41) have been synthesized with 58%-95% yields. The compounds were characterized by using different spectroscopic techniques including FT-IR, H-1 NMR, C-13 NMR spectroscopy and mass spectrometry. The synthesized compounds (22-41) and their precursor chalcones (2-21) were evaluated for antitubercular and cytotoxic activities. Additionally, compounds 22-41 were also tested for antimicrobial activity. Among the chalcone series (2-21), compounds 7 and 14 showed significant antitubercular activities (MICs 25.51 and 23.89 mu M, respectively), whereas among benzothiazepines (22-41), compounds 27 and 34 displayed significant antimicrobial (MICs 38.02 mu M, 19.01 mu M) and antitubercular (MIC 18.10 mu M) activities. Compounds 7 and 41 displayed cytotoxic activities with IC50 of 46.03 +/- 1 and 35.10 +/- 2 mu M respectively. All the compounds were evaluated for cytotoxic activity on normal human liver cell lines (L02) and found to be relatively less selective towards this cell line. The most active compounds identified through this study could be considered as potential leads for the development of drugs with possible antimicrobial, antitubercular, and cytotoxic activities.

Specific and tunable modification to the optical properties of single-wall carbon nanotubes (SWCNTs) is demonstrated through direct encapsulation into the nanotube interior of guest molecules with widely varying static dielectric constants. Filled through simple ingestion of the guest molecule, each SWCNT population is demonstrated to display a robust modification to absorbance, fluorescence, and Raman spectra. Over 30 distinct compounds, covering static dielectric constants from 1.8 to 109, are inserted in large diameter SWCNTs (d = 1.104-1.524 nm) and more than 10 compounds in small diameter SWCNTs (d = 0.747-1.153 nm), demonstrating that the general effect of filler dielectric on the nanotube optical properties is a monotonic energy reduction (red-shifting) of the optical transitions with increased magnitude of the dielectric constant. Systematic fitting of the two-dimensional fluorescence-excitation and Raman spectra additionally enables determination of the critical filling diameter for each molecule and distinguishing of overall trends from specific guest-host interactions. Comparisons to predictions from existing theory are presented, and specific guest molecule/SWCNT chirality combinations that disobey the general trend and theory are identified. A general increase of the fluorescence intensity and line narrowing is observed for low dielectric constants, with long linear alkane filled SWCNTs exhibiting emission intensities approaching those of empty SWCNTs. These results demonstrate an exploitable modulation in the optical properties of SWCNTs and provide a foundation for examining higher-order effects, such as due to nonbulk-like molecule stacking, in host-guest interactions in well-controlled nanopore size materials.

The development of the palladium-catalyzed allylic alkylation of in situ generated boron enolates via tandem 1,4-hydroboration is reported. Investigation of the reaction revealed insights into specific catalyst electronic features as well as a profound leaving group effect that proved crucial for achieving efficient allylic alkylation of ester enolates at room temperature and ultimately a highly preparatively useful synthesis of notoriously challenging acyclic all-carbon quaternary stereocenters. The method demonstrates boron enolates as viable pro-nucleophiles in transition-metal catalyzed allylic alkylation, potentially opening up further transformations outside their traditional use.
