  • A Systematic Study of Metal Triflates in Catalytic Transformations of Glucose in Water and Methanol: Identifying the Interplay of Brønsted and Lewis Acidity
    作者:Iurii Bodachivskyi、Unnikrishnan Kuzhiumparambil、D. Bradley G. Williams
    DOI:10.1002/cssc.201900292
    日期:2019.7.19
    the given metal trifloromethanesulfonates (Brønsted or Lewis acidity) dramatically influences the course of reactions, and it is possible to select for disaccharides, fructose, methyl glucosides, or methyl levulinate. Glucose is transformed into a range of value‐added molecules in water and methanol under the action of acidic metal triflates as catalysts, including their analogous Brønsted acid‐assisted
    与给定的金属三氟甲烷磺酸盐相关的特定类型的酸度(布朗斯台德酸或路易斯酸度)会显着影响反应过程,并且可以选择二糖,果糖,甲基葡糖苷或乙酰丙酸甲酯。在酸性金属三氟甲磺酸盐作为催化剂的作用下,包括类似的布朗斯台德酸辅助或布朗斯台德碱改性体系,葡萄糖可在水和甲醇中转化为一系列增值分子。进行了系统的研究,研究了一系列在甲醇和水中的金属三氟甲磺酸酯,确定了每种产品的优选条件。
  • Direct conversion of 1-deoxy-1-nitroalditols to methyl glycofuranosides
    作者:M. Vojtech、M. Petrušová、B. Pribulová、L. Petruš

    日期:2008.5
    Treatment of the sodium nitronate forms of 1-deoxy-1-nitrohexitols with methanolic sulfuric or hydrochloric acid at −30 °C leads to their regiospecific conversion to the corresponding methyl glycofuranosides. The reaction exhibits more pronounced stereoselectivity for 1-deoxy-1-nitroalditols with the 2,3-erythro configuration than with the 2,3-threo substrates and cis methyl glycofuranosides are the
    在-30°C下用甲醇硫酸或盐酸处理1-脱氧-1-硝基己糖醇的亚硝酸钠形式,导致其区域特异性转化为相应的甲基呋喃糖苷。该反应对具有2,3-赤型构型的1-脱氧-1-硝基醛醇的立体选择性高于与2,3-苏式底物的立体选择性,而顺式甲基葡糖呋喃糖苷是主要产物。观察到的立体选择性表明质子化的α-硝基形式的裂解是一个两步过程,包括亲核加成到质子化的碳-氮双键上,然后用双分子亲核取代含氮残基。
  • Kinetically Controlled Fischer Glycosidation under Flow Conditions: A New Method for Preparing Furanosides
    作者:Seiji Masui、Yoshiyuki Manabe、Kohtaro Hirao、Atsushi Shimoyama、Takahide Fukuyama、Ilhyong Ryu、Koichi Fukase
    DOI:10.1055/s-0037-1611643
    日期:2019.3
    Kinetically controlled Fischer glycosidation was achieved under flow conditions. β-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

  • Continuous process for producing methyl glucosides from starch
    申请人:A.E. STALEY MANUFACTURING COMPANY
    公开号:EP0035589A1
    公开(公告)日:1981-09-16
    The present invention is directed to a continuous process for producing hydrocarbyl aldosides, i.e., alkyl aldosides, 1 from carbohydrates and more particularly mixed alkyl glycosides from starch by direct alcoholysis. A carbohydrate, such as starch, is slurried in an alcohol and passed through a heated, confined zone under pressure and other particular conditions in the presence of an acid catalyst to form a mixed alkyl aldoside. According to a preferred embodiment, the converted carbohydrate/alcohol slurry is rapidly cooled after alcoholysis and before recovery of the alkyl aldoside or aldosides. According to another preferred embodiment at least one alkyl aldoside is separated from the resultant alkyl aldoside mixture and the resultant mother liquor is recycled to carbohydrate/alcohol feed slurry. When using starch as carbohydrate and methanol as alcohol, this embodiment optimizes methyl-alpha-D-ghucopyranoside production.
    本发明涉及一种用碳水化合物,特别是用淀粉直接醇解生产烃基醛苷,即烷基醛苷1的连续工艺。碳水化合物(如淀粉)在醇中淤浆,在压力和其他特殊条件下,在酸催化剂的作用下通过加热的密闭区,形成混合烷基醛苷。根据一个优选的实施方案,转化后的碳水化合物/酒精浆液在醇解后和烷基醛苷或醛苷回收前被迅速冷却。根据另一个优选的实施方案,至少有一种烷基醛苷从得到的烷基醛苷混合物中分离出来,得到的母液再循环到碳水化合物/酒精饲料浆液中。当使用淀粉作为碳水化合物和甲醇作为酒精时,该实施方案可优化甲基-α-D-巨吡喃糖苷的生产。
