Kinetically controlled Fischer glycosidation was achieved under flow conditions. beta-Hydroxy-substituted sulfonic acid functionalized silica (HO-SAS) was used as an acid catalyst. This reaction directly converted aldohexoses into kinetically favored furanosides to enable the practical synthesis of furanosides. After optimization of the reaction temperature and residence time, glucofuranosides, galactofuranosides, and mannofuranosides were synthesized in good yields.

Boldenone is an androgenic anabolic steroid intensively used for growth promoting purposes in animals destined for meat production and as a performance enhancer in athletics. Therefore its use is officially banned either in animals intended for consumption or in humans. Because most anabolic steroids are completely metabolized and usually no parent steroid is excreted, metabolite identification is crucial to detect the illegal use of anabolic steroids either in humans or in livestock. 17alpha- and 17beta-boldenone 17-glucuronides were synthesized, purified and characterized in order to provide suitable standards for the identification and quantification of these metabolites.

Enthalpies of combustion and formation are reported for six O-heterocyclic and four N-heterocyclic compounds in crystalline or liquid phases. By the use of estimated enthalpies of fusion and vaporisation, liquid and gas enthalpies of formation were derived and compared with values predicted directly by the NIST Structures and Properties program and by the Pedley method. The results are discussed in relation to ring strain energies and the strength and weaknesses of the predictive methods are compared.

Two binuclear complexes of cobalt(III) have been prepared with 3,3?,4,4?-tetrahydroxy-5,5?-di-tert-butylbenzaldazine (H4thBu) as bis(catecholate) ligand and two different ancillary ligands, 2,2?-bipyridine (bpy) or 2,2?-dipyridylamine (dpa). These compounds were characterized by 1H NMR spectra, electrochemical measurements and UV-Vis spectra. In one case, [Co2(dpa)4(thBu)]2+, electrochemical oxidation of the complexes occurs at the bridges as two closely spaced one-electron couples (E1/2 = 1 mV and 168 mV versus Fc/Fc+). Chemical oxidation of [Co2(dpa)4(thBu)]2+ using Ag+ is observed to occur as a stepwise two-electron process forming [Co2(dpa)4(thBuCat,SQ)]3+ or [Co2(dpa)4(thBuSQ,SQ)]4+ by UV-Vis spectrum. However, [Co2(bpy)4(thBu)]2+ shows no change in electronic spectrum under the same conditions of oxidation. This illustrates the dependence of redox properties of the binuclear Co(III) complexes on the nature of the nitrogen-donor ancillary ligands. In this report we discuss the effect of two different nitrogen-donor ancillary ligands on the0 oxidation behavior of binuclear Co(III) complexes.

Catalysts are substances that increase the reaction rate of a chemical reaction without being consumed in the process. Introducing a new discovery about 10343-06-3, Name is 2,3,4,6-Tetra-o-acetyl-D-glucopyranose, Synthetic Route of 10343-06-3.

Upgrading pyrolysis oil by hydrodeoxygenation (HDO) is a promising route for the production of advanced biofuels. The proper reaction conditions and catalysts are important for the success of this process. Previously our research group investigated the ratio of Zn and Pd on the synergistic effect for HDO bio-oil upgrading. This present research focuses on determining the optimal reaction conditions for HDO conversion of pyrolysis oil produced from pine sawdust. Temperatures of 150, 200 and 250 C and hydrogen pressures of 1.38, 2.76 and 4.14 MPa were evaluated. Syngas, liquids and coke were the primary products evaluated. Syngas was characterized using a Gas chromatography (GC). The liquids were characterized using a Gas chromatography-mass spectrometry (GC-MS). Increasing reaction temperature resulted in increased coke yields. Treatment at 250 C and 1.38 MPa resulted in the highest hydrocarbon content (6.06%). The treatment at 200 C and 1.38 MPa produced the largest amounts of hydrocarbons in C6-C12 range (5.07%). The physicochemical characterizations further support the GCMS results. Syngas analysis revealed that higher hydrogen pressure leads to increased hydrogen consumption and results in more oxy-compounds conversion to hydrocarbons. The syngas analysis also supports the liquid analysis result.

Enzyme inhibitors cause a decrease in the reaction rate of an enzyme-catalyzed reaction by binding to a specific portion of an enzyme. Irreversible inhibitors are therefore the equivalent of poisons in heterogeneous catalysis. 31608-22-7, C9H17BrO2.

All-cis-14,15-epoxyeicosa-5,8,11-trienoic acid (14,15-EET) is a labile, vasodilatory eicosanoid generated from arachidonic acid by cytochrome P450 epoxygenases. A series of robust, partially saturated analogues containing epoxide bioisosteres were synthesized and evaluated for relaxation of precontracted bovine coronary artery rings and for in vitro inhibition of soluble epoxide hydrolase (sEH). Depending upon the bioisostere and its position along the carbon chain, varying levels of vascular relaxation and/or sEH inhibition were observed. For example, oxamide 16 and N-iPr-amide 20 were comparable (ED50 1.7 muM) to 14,15-EET as vasorelaxants but were approximately 10-35 times less potent as sEH inhibitors (IC50 59 and 19 muM, respectively); unsubstituted urea 12 showed useful activity in both assays (ED50 3.5 muM, IC50 16 nM). These data reveal differential structural parameters for the two pharmacophores that could assist the development of potent and specific in vivo drug candidates.
