Formula: C8H8O2. I found the field of Chemistry very interesting. Saw the article Direct Synthesis of Phenols from Phenylboronic Acids in Aqueous Media Catalyzed by a Cu(0)-Nanoparticles Biohybrid published in 2020.0, Reprint Addresses Palomo, JM (corresponding author), Inst Catalysis CSIC, Dept Biocatalysis, Cantoblanco Campus UAM, Madrid 28049, Spain.. The CAS is 99-93-4. Through research, I have a further understanding and discovery of 4′-Hydroxyacetophenone.

Selective hydroxylation of different phenylboronic acids to phenols was successfully carried out by using Cu nanoparticles-enzyme hybrid catalysts in water and room temperature. Different Cu-enzyme hybrids containing Cu(II), Cu(I) and Cu(0) nanoparticles species respectively were tested on the monohydroxylation of phenylboronic acid under these mild conditions being hybrids containing Cu(0)NPs the best catalysts, with total selectivity and formation of phenol as unique product. Also, the addition of hydrogen peroxide or the increase of reaction temperature were tested but did not improved these results. The substrate scope was also demonstrated and the Cu(0)NPs hybrid showed excellent results in the monohydroxylation of differento-, m-, p-substituted phenylboronic acid with final yields >95 %. This catalyst showed excellent recyclability after 5 cycles of use.

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.

This study aimed to characterize the antioxidant potential, bioactive and volatile compounds of the stones from fruits of Cornus mas. Both fresh and roasted stones show a high antioxidant potential (166.48-509.74 mu mol TE/g dw stones), which significantly depends on the cultivars. The roasted stones preserved 43.6% (DPPH; ‘Raciborski’) to 97.2% (FRAP; ‘Alesha’) of the antioxidant activity of the non-roasted stones. In the stones, two iridoids and ellagic acid were determined. During roasting, loganic acid remained stable, whereas cornuside was completely degraded. The analyses showed a 30-fold increase in the concentration of ellagic acid and in the formation of two of its derivatives. The major aroma compound of the roasted stones was furfural, but we also identified 18 pyrazine derivatives. This study is the first attempt to valorize Cornelian cherry stones via roasting. The roasted stones can be a coffee substitute, or aromatic and bioactive additions to cereal coffees.

The oil and gas industry suffers from severe economic impact due to the corrosion of pipelines during the industrial oil-well acidizing process and because of the sweet corrosion of steel. One of the most common solutions to counter this issue is applying organic compounds as corrosion inhibitors. Conventionally used inhibitors are quite cumbersome to synthesize, are costly, and most are toxic. Therefore, there exists a need for research and development of novel, cost-effective, and eco-friendly corrosion inhibitors showing efficient inhibition performance. The present work describes the basics of corrosion, its economic impact, and the main strategies to counter this issue. Fundamentals of sweet corrosion, the mechanism involved, the influence of various governing factors, and the limitations of the existing inhibitor chemistries are explained. Some of the prominent classes of the environmentally benign sweet corrosion inhibitors such as the biopolymers, heterocyclic molecules, and pharmaceutical products are also outlined. The focus is on the recent research work in this area, and some of the prospective research aspects are envisaged. (C) 2020 Published by Elsevier B.V.

A second-generation m-phenolsulfonic acid-formaldehyde resin (PAFR II) catalyst was prepared by condensation polymerization of sodium m-phenolsulfonate and paraformaldehyde in an aqueous H2SO4 solution. This reusable, robust acid resin catalyst was improved in both catalytic activity and stability, maintaining the characteristics of the previous generation catalyst (p-phenolsulfonic acid-formaldehyde resin). PAFR II was applied in the batchwise and continuous-flow direct esterification without water removal and provided higher product yields in continuous-flow esterification than any other commercial ion-exchanged acid catalyst tested.

A virtual screening conducted with nearly 4 000 000 compounds from lead-like and fragment-like subsets enabled the identification of a small-molecule inhibitor (1) of the Trypanosoma cruzi cruzain enzyme, a validated drug target for Chagas disease. Subsequent comprehensive structure-based drug design and structure-activity relationship studies led to the discovery of carbamoyl imidazoles as potent, reversible, and competitive cruzain inhibitors. The most potent carbamoyl imidazole inhibitor (45) exhibited high affinity with a K-i value of 20 nM, presenting both in vitro and in vivo activity against T. cruzi. Furthermore, the most promising compounds reduced parasite burden in vivo and showed no toxicity at a dose of 100 mg/kg. These carbamoyl imidazoles are structurally attractive, nonpeptidic, and easy to prepare and synthetically modify. Finally, these results further advance our understanding of the noncovalent mode of inhibition of this pharmaceutically relevant enzyme, building strong foundations for drug discovery efforts.

I found the field of Pharmacology & Pharmacy very interesting. Saw the article The tyrosinase-inhibitory effects of 2-phenyl-1,4-naphthoquinone analogs: importance of the (E)–phenyl-,-unsaturated carbonyl scaffold of an endomethylene type published in 2019.0. Recommanded Product: m-Methoxyphenol, Reprint Addresses Moon, HR (corresponding author), Pusan Natl Univ, Coll Pharm, Busan 609735, South Korea.; Chun, P (corresponding author), Inje Univ, Coll Pharm, Gimhae 50834, Gyeongnam, South Korea.; Chun, P (corresponding author), Inje Univ, Inje Inst Pharmaceut Sci & Res, Gimhae 50834, Gyeongnam, South Korea.. The CAS is 150-19-6. Through research, I have a further understanding and discovery of m-Methoxyphenol

In order to investigate the effect of the (E)–phenyl-,-unsaturated carbonyl scaffold of an endomethylene type on tyrosinase inhibition, 2-phenyl-1,4-naphthoquinone derivatives were synthesized by Michael addition of substituted benzenes to 1,4-naphthoquinone and subsequently an auto-oxidation. Most of the derivatives potently inhibited mushroom tyrosinase and four derivatives, including 1c (IC50=22.00 +/- 1.63M), more potently inhibited mushroom tyrosinase than kojic acid (IC50=37.86 +/- 2.21M). Cell-based assays using B16F10 cells (a melanoma cell line) showed 1c dose-dependently suppressed melanin production and more potently inhibited tyrosinase activity than kojic acid. Docking simulation results between 1c and tyrosinase and a kinetic study suggest that 1c is a competitive inhibitor that binds to the active site of tyrosinase. These results support that anti-melanogenic effect of naphthoquinone derivatives results from their tyrosinase inhibiting activity and the (E)–phenyl-,-unsaturated carbonyl scaffold of an endomethylene type can confer tyrosinase-inhibitory activity.

Herein, we report a green, chromatography-free Appel chlorination and bromination in both catalytic and stoichiometric form. Improved sustainability was achieved via the effective replacement of chlorinated solvents with dimethyl carbonate and the use of triphenylphosphine oxide (PPh3O) as a recyclable organocatalyst. The substrate scope of this halogenated solvent-free reaction was shown to be analogous to a contemporary methodology, and removal and recovery of PPh3O from the desired products were effectively demonstrated. Investigations into the catalytic cycle were conducted, and REACT-IR was demonstrated to be an effective method of reaction monitoring in situ. Optimized methodology was applied to the synthesis of 1-bromo-4-(1-bromoethyl)benzene, a key building block employed during the discovery of a GSK fatty acid synthase inhibitor.
