    A Convenient Synthesis of a Cardiac Sugar: “D-Digitalose”
    摘要:
    D-Digitalose (6-deoxy-3-O-methyl-D-galactose), a biologically important sugar that is found in some cardiac glycosides, was synthesized from D-galactose via 3-O-methyl-1,2,5-O-orthodichloroacetyl-alpha-D-galactofuranose.

    摘要:
    使用醚合三氟化硼作为促进剂,在二恶烷中回流使两种己糖和两种戊糖与两个当量的三氯乙醛反应。在每种情况下,主要产物是外-1,2- O-三氯亚乙基醛呋喃糖,其产率各不相同,与以前在三氯乙醛作为溶剂中使用硫酸或盐酸作为促进剂以较低产率获得的产物相同。对剩余产物混合物的仔细分馏表明,在大多数情况下也产生了乙缩醛环中的另一种异构体,但只有少量的两种 1,2- O还产生了-三氯亚乙基亚吡喃糖异构体。此外,还发现了非常少量的其他产品,这些产品来源于三氟化硼醚合物和溶剂。提出了一种涉及限速缩醛闭环的机制来解释呋喃糖衍生物的形成,而不是吡喃糖衍生物。对取代衍生物的去除三氯亚乙基缩醛的方法进行了研究,发现涉及用氢化三丁基锡还原的方法是有效的。

  • Syntheses and Characterization of New 3-O-Allyl Ether Chloralose Derivatives
    作者:Fatma Çetin Telli
    DOI:10.14233/ajchem.2015.17975
    日期:——
    The new 3-O-allyl ether derivatives of sugar were synthesized with high yield and mild reaction conditions. The synthesis of 3-O-acetylchloralose derivatives (5-8) and 3-O-allyl ether chloralose derivatives (9-12) were carried out. These new 3-O-allyl ether of chloralose derivatives are potential monomers for the synthesis of new glycopolymers.
    新型3-O-烯丙基醚糖衍生物在高产率和温和反应条件下合成成功。合成了3-O-乙酰氯醇糖衍生物(5-8)和3-O-烯丙基醚醇糖衍生物(9-12)。这些新型3-O-烯丙基醚醇糖衍生物是合成新型糖聚合物的潜在单体。
  • Synthesis, characterization and non-isothermal decomposition kinetic of a new galactochloralose based polymer

    A glycopolymer, poly(3-O-methacroyl-5,6-O-isopropylidene-1,2-O-(S)-trichloroethylidene-alpha-D-galactofuranose) (PMIPTEG) was synthesized from the sugar-carrying methacrylate monomer, 3-O-methacroyl-5,6-O-isopropylidene-1,2-O-(S)-trichloroethylidene-alpha-D-galactofuranose (MIPTEG) via conventional free radical polymerization with AIBN in 1,4-dioxane. The structures of glycomonomer and their polymers were confirmed by UV-vis, FT-IR, H-1 NMR, C-13 NMR, GPC, TG/DTG-DTA, DSC, and SEM techniques. SEM images showed that PMIPTEG had a straight-chain length structure. On the other hand, the thermal decomposition kinetics of polymer were investigated by means of thermogravimetric analysis in dynamic nitrogen atmosphere at different heating rates. The apparent activation energies for thermal decomposition of the PMIPTEG were calculated using the Kissinger, Kim-Park, Tang, Flynn-Wall-Ozawa (FWO), Kissinger-Akahira-Sunose (KAS) and Friedman methods and were found to be 100.15, 104.40, 102.0, 102.2, 103.2 and 99.6 kJ/mol, respectively. The most likely process mechanism related to the thermal decomposition stage of PMIPTEG was determined to be a D deceleration type in terms of master plots results. (C) 2013 Elsevier Ltd.
