Organocatalyzed Deracemization of Delta(2)-Pyrrolin-4-ones

Racemic pyrrolin-4-ones, accessible from a-amino acids, undergo asymmetric stereoselective organocatalyzed 1,4-additions to trans-beta-nitrostyrenes (up to 98% ee; dr up to 97: 3). From a series of typical organocatalysts, the best performance was achieved using (+)-camphor-1,3-diamine-derived bifunctional organocatalysts. A broad substrate scope and some follow-up modifications have been demonstrated.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 1953-02-2. COA of Formula: https://www.ambeed.com/products/1953-02-2.html.

Nitrile-Facilitated Proton Transfer for Enhanced Oxygen Reduction by Hybrid Electrocatalysts

To enable efficient energy conversion schemes for our society in the future, breakthroughs in precise thermodynamic and kinetic control of the underlying redox reactions are necessary. Hybrid bilayer membranes (HBMs), comprising a self-assembled monolayer (SAM) covered by a lipid membrane, have been developed recently to regulate the performance of HBM-embedded electrocatalysts. A major technological roadblock in HBM development is the inability to facilitate proton transfer under alkaline conditions where nonprecious metal (NPM) catalysts can rival the performance of their precious metal counterparts. Here, we synthesized proton carriers bearing nitrile groups found in protonophores. These bioinspired proton carriers can facilitate transmembrane proton delivery to an HBM-supported Cu oxygen reduction reaction (ORR) catalyst under alkaline conditions. Our stimuli-responsive proton regulators can turn on the activity of the ORR catalyst on-demand, thereby opening doors to investigate how proton transfer kinetics govern the performance of electrocatalysts for renewable energy conversion processes.

Therefore, this conceptually novel strategy might open impressive avenues to establish green and sustainable chemistry platforms. 5306-85-4, you can contact me at any time and look forward to more communication. Application In Synthesis of (3R,3aR,6S,6aR)-3,6-Dimethoxyhexahydrofuro[3,2-b]furan.

Tribological behaviors of the water-lubricated rubber bearings under different lubricated conditions

Purpose – This study aims to evaluate the tribological behavior of water-lubricated rubber bearings sliding against stainless steel under different lubricate conditions. Design/methodology/approach – The water-lubricated rubber bearings under various normal loads and sliding speeds were carried out on the ring-block friction test, and the wear morphology is test conducted by using scanning electron microscope. Findings – The results indicate that the surface of water-lubricated rubber bearings has a more alternative friction coefficient and wear rate under seawater than other lubricate conditions. The seawater not only acts as a lubricating medium but also brings microstructure while corroding the rubber interface, thereby further enhancing the lubricating effect and storing abrasive debris. Originality/value – In this paper, tribological properties of the water-lubricated rubber bearing on ring-block friction test has been investigated. Water-lubricated rubber bearing was carried out on various lubricate conditions, and the friction coefficient, wear rate and worn surface were analyzed. Also, the effects of sliding speeds were investigated. Peer review – The peer review history for this article is available at: https://publons.com/publon/10.1108/ILT-06-2020-0204/

EFFECTS OF MYOSMINE ON ANTIOXIDATIVE DEFENCE IN RAT LIVER

Myosmine [3-(1-pyrrolin-2-yl) pyridine] is an alkaloid structurally similar to nicotine, which is known to induce oxidative stress. In this study we investigated the effects of myosmine on enzymatic and nonenzymatic antioxidative defence in rat liver. Wistar rats received a single i.p. injection of 19 mg kg(-1) of myosmine and an oral dose of 190 mg kg(-1) by gavage. Nicotine was used as a positive control. Through either route of administration, myosmine altered the hepatic function by decreasing the levels of reduced glutathione, superoxide dismutase, and glutathione peroxidase activities on one hand and by increasing malondialdehyde, catalase, and glutathione reductase activity on the other. Compared to control, both routes caused significant lipid peroxidation in the liver and altered hepatic enzymatic and non-enzymatic antioxidative defences. The pro-oxidant effects of myosmine were comparable with those of nicotine.
