In a patent, introducing its new discovery.

The oxidant, 4-acetylamino-2,2,6,6-tetramethylpiperidine-oxoammonium tetrafluoroborate in pyridine/CH2Cl2, is reported to be an excellent reagent for the conversion of hemiacetals to lactones. Specifically, the conversion of 1-O unprotected sugars to their corresponding aldonolactones is achieved in high yields. The basic reaction conditions partially overcome some disadvantages reported for oxoammonium-type oxidants, namely the inability to run the reaction in the presence of acid-labile groups and in the presence of beta-oxygens.

Application of 10343-06-3, Catalysts are substances that increase the reaction rate of a chemical reaction without being consumed in the process. 10343-06-3, Name is 2,3,4,6-Tetra-o-acetyl-D-glucopyranose, molecular formula is C14H20O10. In a Article£¬once mentioned of 10343-06-3

We have prepared glucose and cellobiose conjugates at the phenolic 3- and hydroxylic 17-positions of the pure anti-estrogenic compound fulvestrant (ICI 182,780), which has recently been approved in the USA for the treatment of advanced postmenopausal breast cancer. Glycosylation at the 17-position was achieved most effectively using pivaloyl protection of the sugar imidates employed, which we found suppressed the competing transacylation reaction and led to improved yields of the product glycosides.

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.

Application of 10343-06-3, An article , which mentions 10343-06-3, molecular formula is C14H20O10. The compound – 2,3,4,6-Tetra-o-acetyl-D-glucopyranose played an important role in people’s production and life.

Acacetin and resveratrol 3,5-di-O-beta-glucopyranoside were synthesized from naturally abundant naringin and piceid in 65% and 62% overall yield, respectively. The key steps were the regioselective deacetylation of the peracetates of the glycosylated forms with Candida antarctica lipase B (Novozym 435) and Burkholderia cepacia lipase (Amano PS-IM). Deacetylation occurred exclusively at the least hindered position of the aromatic moieties and all acetyl groups in the sugar side chain remained intact. This excellent selectivity enabled regiospecific transformation of the liberated phenolic hydroxy groups, resulting in efficient synthesis of the target molecules.

The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.10343-06-3, Name is 2,3,4,6-Tetra-o-acetyl-D-glucopyranose, molecular formula is C14H20O10. In a Article£¬once mentioned of 10343-06-3, category: Tetrahydropyrans

The chemical synthesis of pyridoxine-5?-beta-D-glucoside (5?-beta-PNG) was investigated using various glucoside donors and promoters. Hereby, the combination of alpha4,3-O-isopropylidene pyridoxine, glucose vested with different leaving and protecting groups and the application of stoichiometric amounts of different promoters was examined with regards to the preparation of the twofold protected PNG. Best results were obtained with 2,3,4,6-tetra-O-acetyl-D-glucopyranosyl fluoride and boron trifluoride etherate (2.0 eq.) as promoter at 0 C (59%). The deprotection was accomplished stepwise with potassium/sodium hydroxide in acetonitrile/water followed by acid hydrolysis with formic acid resulting in the chemical synthesis of 5?-beta-PNG.

A catalytic method is developed for the diastereoselective acylation of the anomeric hydroxyl group in diverse carbohydrates to form either alpha- or beta-anomeric esters. While exclusive formation of the beta-isomer was observed in most sugar substrates with one enantiomer of the chiral catalyst, moderate to high alpha-selectivity was obtained by using the other enantiomer of the chiral catalyst. The resulting alpha- and beta-anomeric esters have very different reactivity toward a reduction reaction.

A series of dihydroartemisinin derivatives containing a sugar moiety was prepared in the search for analogues with good water solubility and high antimalarial activity. The preparation of the new compounds were achieved by treatment of dihydroartemisinin (2) with chlorotrimethylsilane in pyridine solution at -10 C to give a nearly quantitative yield of 10-O- (trimethylsilyl)dihydroartemisinin (3), which was then condensed with 1- hydroxypolyacetylated sugars 5 to give dihydroartemisinin derivatives 7a-d. Deacetylation of intermediates 7 gave the desired sugar derivatives 8. The resulting derivatives, tested in vitro against Plasmodium falciparum, were found to be more effective against W-2 than D-6 clones and were not cross- resistant with existing antimalarials. Trimethylsilylated compound 3 is more effective than derivatives 7a-d, which possess activity comparable to or better than that of artemisinin itself. Deacetylated compounds 8a-d were substantially less active than 7 in both cell lines. In P. berghei-infected mice, 7a-c showed 5/5, 2/5, and 3/5 cures, respectively, at 320 mg/kg per day x 3, whereas 7d showed no activity at the same dosage. However, 7d did prolong the life span in 3/5 of the infected mice at 640 mg/kg per day x 3 dose level. Trimethylsilylated compound 3 was also the most effective among the compounds studied, with 5/5 cures at 80 mg/kg per day x 3. The deacetylated sugar derivatives 8a-d showed only slight in vivo antimalarial activity.
