The tandem reaction is a growing field to yield important advances toward green and sustainable chemistry. Herein, we report a bifunctional manganese oxide catalyst with an interface binding redox phase (alpha-MnO2) and a basic phase (NaxMnO2). The molar ratio of NaOH/Mn plays a great role in the formation of alpha-MnO2/NaxMnO2. The sodium cation is essential for the formation of a basic NaxMnO2 phase while the potassium cation promotes the formation of a redox-active alpha-MnO2 phase. The interface structure of alpha-MnO2/NaxMnO2 geometrically favors the ammoxidation-Pinner tandem reaction to synthesize imidates in a 58-96% yield from aldehydes. Thus a phase collaborative effect is observed. In the ammoxidation process, the redox cycle of MnIV/MnIII is involved and the lattice oxygen in the alpha-MnO2 phase acts as an active oxygen species. The O-H in methanol is activated and dissociated on the basic sites of NaxMnO2 to the adsorbed methoxyl species to facilitate the Pinner synthesis. This approach bypasses the conventional synthesis of imidates, which suffer from harsh reaction conditions and the requirement for multiple steps.

We’ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, the role of 41717-32-2, and how the biochemistry of the body works.Reference of 41717-32-2

A novel palladium-catalyzed selective hydroxylfluorination of gem-difluoroalkenes has been developed. By employing easily obtainable gem-difluoroalkenes and NFSI as the fluorine source, the scope, advantages, and limitations of this reaction were investigated. The reaction presents an efficient synthesis to afford a series of alpha-trifluoromethyl alcohols in good to excellent yields. Furthermore, this reaction probably proceeds via oxidation of Pd0 to PdII fluoride complex by NFSI, followed by fluoropalladation of gem-difluoroalkenes to generate an alpha-trifluoromethylbenzyl?Pd intermediate. And this strategy offers more possibilities for the construction of other bonds, such as C?C, C?N and C?S.

A robust and high-yielding radiochemical synthesis of 11C-N-cyanobenzamides using a palladium-mediated aminocarbonylation with 11C-CO, aryl halides and cyanamide is described. The bidentate ligand 1,1?-bis(diphenylphosphino)ferrocene provided 11C-N-cyanobenzamides from aryl-iodides, bromides, triflates and even chlorides in 28-79% radiochemical yield after semi-preparative HPLC.

Two series of analogues of riluzole, a blocker of excitatory amino acid mediated neurotransmission, have been synthesized: monosubstituted 2- benzothiazolamines and 3-substituted derivatives. Of all the compounds prepared in the first series, only 2-benzothiazolamines bearing alkyl, polyfluoroalkyl, or polyfluoroalkoxy substituents in the 6-position showed potent anticonvulsant activity against administration of glutamic acid in rats. The most active compounds displaying in vivo ‘antiglutamate’ activity were the 6-OCF3 (riluzole), 6-OCF2CF3, 6-CF3, and 6-CF2CF3 substituted derivatives with ED50 values between 2.5 and 3.2 mg/kg i.p. Among the second series of variously substituted benzothiazolines, compounds as active as riluzole or up to 3 times more potent were identified in two series: benzothiazolines bearing a beta-dialkylaminoethyl moiety and compounds with an alkylthioalkyl chain and their corresponding sulfoxides and sulfones. The most potent derivatives were 2-imino-3-(2-methylthio)- and 2-imino-3-(2- methylsulfinyl)-ethyl-6-trifluoromethoxybenzothiazolines (61 and 64, ED50 = 1.0 and 1.1 mg/kg i.p., respectively). In addition, intraperitoneal administration of some of the best benzothiazolines protected mice from mortality produced by hypobaric hypoxia.

The use of detergents with enzymatic activity is very popular if we consider their real economic advantages – reducing energy and water consumption but also reducing the environmental impact by using more biodegradable components related to organic and inorganic components. The purpose of our study was to evaluate the impact of environmental factors such as the variability of water hardness in the public water supply network and the temperature applied to the amylolytic, lipolytic and proteolytic enzyme activity of 6 detergents available on the market. The determinations were performed by modified methods from the European Pharmacopoeia 8th Edition in determination the enzymatic activity of the pancreas powder. The determinations show a significant influence of increased water hardness on lipase and protease activity in detergent (p <0.01 *) between extreme hardness values, while amylolytic activity does not vary significantly with increasing water hardness. A reaction mechanism is the microscopic path by which reactants are transformed into products. Each step is an elementary reaction.

Pyrophthalones VII.Synthesis and anti-inflammatory activity of 2-(4-pyridinyl)indane-1,3-diones diversely substituted on the benzene ring.Access routes to 2-(1,4-dihydro 4-pyridinylidene) indane-1,3-diones diversely substituted on the benzene ring are studied.The regiospecific attack of these beta diketoenamines by alkyl iodides leads to N-substituted compounds.These derivatives may be obtained by any of three possible methods: (1) condensation of 4-methyl pyridine with ethyl phthalates in the absence of catalyst; (2) oxidative condensation of N-alkyl-pyridinium bromides with indane-1,3-diones; (3) aminolysis of 2-(4-4H-pyranylidene) indane-1,3-diones.Pharmacomodulation by the introduction of oxygen or sulfur containing functions (ether, thioether, alcohol, ketone, acid, ester, amide) on the nitrogen of the basic molecule is not very fruitful; only the acetic derivative 19 manifests marked antiinflammatory activity unaccompanied by anti-coagulant action.The presence of chloro, nitro or methoxyl groups on 5 after N-substitution by ethyl or piperidinylethyl groups appears to be more favorable.The most active compound 57 decreases prostaglandin production and leukocyte migration without affecting either cyclooxygenase or 5-lipoxygenase.Its interference, direct or indirect, with phospholipasic A2 activity may be envisaged in particular.Keywords – 2-(4-pyridinyl)indane-1,3-diones / heterocyclic beta diketoenamines / partition coefficient / anti-inflammatory activity / mechanism of action

The high temperature curing reactions of oligomers bearing two phenylethynyl groups have previously been utilized to produce attractive new materials, but are not well understood. A model aryl ether imide compound with one such moiety was used to elucidate some of the chemistry occurring during these processes. It was demonstrated that oligomeric molecular weight soluble products were formed by thermal initiation at 375 C under nitrogen during these reactions, along with low molecular weight fragments derived from the model compound. These fragments were demonstrated to contain aliphatic protons in place of the phenylethynyl group and constitute about 5% of the overall material. Reactions of the model compound with deuterated biphenyl indicated that the reactive intermediates formed from the phenylethynyl moiety are able to abstract aromatic deuterium atoms in the presence of aromatic protons. However, these fragments appear to be side products not directly involved with the main curing reactions that occur after most of the carbon-carbon triple bonds have been reacted.
