In homogeneous catalysis, the catalyst is in the same phase as the reactant. The number of collisions between reactants and catalyst is at a maximum.In a patent, 111769-27-8, name is (R)-Tetrahydrofuran-3-amine 4-methylbenzenesulfonate, introducing its new discovery. Product Details of 111769-27-8

A class of potent, nonsteroidal, selective indazole ether-based glucocorticoid receptor modulators (SGRMs) was developed for the inhaled treatment of respiratory diseases. Starting from an orally available compound with demonstrated anti-inflammatory activity in rat, a soft-drug strategy was implemented to ensure rapid elimination of drug candidates to minimize systemic GR activation. The first clinical candidate 1b (AZD5423) displayed a potent inhibition of lung edema in a rat model of allergic airway inflammation following dry powder inhalation combined with a moderate systemic GR-effect, assessed as thymic involution. Further optimization of inhaled drug properties provided a second, equally potent, candidate, 15m (AZD7594), that demonstrated an improved therapeutic ratio over the benchmark inhaled corticosteroid 3 (fluticasone propionate) and prolonged the inhibition of lung edema, indicating potential for once-daily treatment.

One of the major reasons for studying chemical kinetics is to use measurements of the macroscopic properties of a system, Safety of Furan-2,4(3H,5H)-dione, such as the rate of change in the concentration of reactants or products with time.In a article, mentioned the application of 4971-56-6, Name is Furan-2,4(3H,5H)-dione, molecular formula is C4H4O3

A series of novel 3-acetyl-4-hydrazinyl-5,5-disubstitutedtetronic acid and (E/Z)-3-(1-hydrazinylethyli-dene)-5,5-disubstitutedfuran-2,4-dione derivatives were designed and synthesized, and four methyl 5-methyl pyrazole-4-carboxylate were obtained unexpectedly. Their structures were confirmed by high-resolution mass spectrum (HR-ESI-MS), 1H NMR, 13C NMR spectral data and X-ray diffraction. The bioassay results of the hydrazinyl compounds along with the amino analogues indicated that some compounds exhibited moderate to excellent fungicidal activities against phytopathagens. For example, compounds 5G, 5H, 5I and 5i showed 100% in vivo control efficacy against Colletotrichum lagenarium, and compound 5G also exhibited 100% in vivo control efficacy against Erysiphe graminis, Puccinia polysora and Colletotrichum lagenarium at 400 mug/mL. Compounds 5b, 5E and 6F showed 100% mortality against Plutella xylostella, compounds 6A, 6g and 6H exhibited 100% mortality against Myzus persicae, and compound 6b showed 100% mortality against Tetranychus cinnabarinus at 600 mug/mL. The 5,5-spiro cyclohexyl moiety significantly improved the fungicidal activity of the tetronic acid derivatives, and the introduction of the substituted hydrazino group to the furan-2,4-dione skeleton led to higher insecticidal and acaricidal activities. 5G and 5i were found to have the most potential to be further modified for searching new fungicide as the lead compounds.

The mechanism of fast pyrolysis of cellulose has been studied by using an analytical pyrolyzer coupled with a gas chromatography-mass spectrometry set-up (Py-GC/MS). The results showed that the main products comprised pyrans such as levoglucosan and levoglucosenone, furans such as furfural and 5-hydroxymethyl furfural, and linear small molecular chemicals such as acetaldehyde and 1-hydroxy-2-propanone. The compositions of products from fast pyrolysis of cellubiose and glucose were similar to that from cellulose, but with higher furan contents and lower pyran contents. Based on the experimental results, density functional theory (DFT) studies were carried out to deduce the pyrolysis mechanism of cellulose. The results showed the formation of 5-hydroxymethyl furfural from d-glucopyranose unit to be easier than the formation of levoglucosan, in agreement with the experimental results. The deduced mechanism of reaction pathways in cellulose pyrolysis provides insight into the pyrolysis behavior of cellulose and allows modification of previously proposed related mechanisms.

A transition-metal-free protocol capable of synthesizing diarylated aniline derivatives is reported. This method could be further employed to prepare aryl alkyl ethers. A wide range of thioethers, anilines, as well as alcohols were tolerated thanks to the mild reaction conditions. The strength of our method was demonstrated by performing a gram-scale reaction (20 mmol) followed by conversion of the nitrile group into synthetically useful aldehyde, ketone, and carboxylic acid.
