  • Synthesis, Biological Evaluation, WAC and NMR Studies of<i>S</i>-Galactosides and Non-Carbohydrate Ligands of Cholera Toxin Based on Polyhydroxyalkylfuroate Moieties
    作者:Javier Ramos-Soriano、Ulf Niss、Jesús Angulo、Manuel Angulo、Antonio J. Moreno-Vargas、Ana T. Carmona、Sten Ohlson、Inmaculada Robina
    DOI:10.1002/chem.201302786
    日期:2013.12.23
    The synthesis of several non‐carbohydrate ligands of cholera toxin based on polyhydroxyalkylfuroate moieties is reported. Some of them have been linked to D‐galactose through a stable and well‐tolerated S‐glycosidic bond. They represent a novel type of non‐hydrolyzable bidentate ligand featuring galactose and polyhydroxyalkylfuroic esters as pharmacophoric residues, thus mimicking the GM1 ganglioside
    报道了基于聚羟烷基糠酸酯部分的几种霍乱毒素的非碳水化合物配体的合成。其中一些已通过稳定且耐受良好的S与D-半乳糖相连糖苷键。它们代表了一种新型的不可解的二齿配体,其特征在于半乳糖和聚羟烷基糠酸酯为药效基团残基,从而模仿了GM1神经节苷脂。通过弱亲和色谱法(WAC)测量了新化合物对霍乱毒素的亲和力。还通过饱和转移差异NMR实验研究了最佳候选物与该毒素的相互作用,该实验可以鉴定与蛋白质相互作用的配体的结合表位。有趣的是,基于聚羟烷基糠酸酯结构的非碳水化合物模拟物显示出最高的亲和力。
  • Using DMF as Both a Catalyst and Cosolvent for the Regioselective Silylation of Polyols and Diols
    作者:Jian Lv、Tao Luo、Dapeng Zou、Hai Dong
    DOI:10.1002/ejoc.201901195
    日期:2019.10.9
    discovered to be a good catalyst in the regioselective silylation of unprotected carbohydrates, although the silylation using DMF as a solvent has been a common method for more than 40 years. It has been demonstrated that a complex with a 1:1 ratio of the binding partners can be formed between TBSCl and DMF and has an association constant of 12/M, thus activating the silylation.
    尽管使用DMF作为溶剂的甲硅烷基化已超过40年,但已发现DMF是未保护碳水化合物在区域选择性甲硅烷基化中的良好催化剂。已经证明,可以在TBSC1和DMF之间形成具有1:1比例的结合配偶体的复合物,并且其缔合常数为12 / M,从而激活甲硅烷基化。
  • Regioselective Benzylation of Diols and Polyols by Catalytic Amounts of an Organotin Reagent
    作者:Hengfu Xu、Yuchao Lu、Yixuan Zhou、Bo Ren、Yuxin Pei、Hai Dong、Zhichao Pei
    DOI:10.1002/adsc.201301152
    日期:2014.5.26
    An efficient one‐pot method for the selective benzylation of diols and polyols using 0.1 equiv. of organotin reagents and tetrabutylammonium bromide as catalyst has been developed. The diols and polyols containing a cis‐vicinal diol were regioselectively benzylated in 70–94% isolated yields. A catalytic reaction mechanism was also proposed.
    一种高效的一锅法,可使用0.1当量对二醇和多元醇进行选择性苄基化。已开发出有机锡试剂和四丁基溴化铵作为催化剂。含顺式-邻位二醇的二醇和多元醇被区域选择性地苄基化,分离产率为70-94%。还提出了催化反应机理。
  • Extension of the ring oxygen helicity rule to the phenyl- and phenyl-1-thio-glycosides
    作者:Katsunori Kohata、Toshio Konno、Hiroshi Meguro
    DOI:10.1016/0040-4039(80)80174-2
    日期:1980.1
    Circular Dichroism (CD) of the phenyl- and phenyl-1-thio-β(or α)-d-glycosides were studied. The sign and the rotational strength of Band C, the shortest and the strongest band between 180∼210 nm, were associated with the anomeric configuration and conformation in the same manner as the σ→σ* band of the ring oxygen in the 1-alkyl- and 1-alkyl-thio-glycosides. This result suggested that the ring oxygen
    研究了苯基和苯基-1-代β(或α)-d-糖苷的圆二色性(CD)。180〜210 nm之间最短和最强的能带C的符号和旋转强度与异头构型和构象相关联,其方式与1-烷基中环氧的σ→σ*带相同-和1-烷基-代糖苷。该结果表明,环氧螺旋度规则可以扩展到苯基-和苯基-1-代糖苷。
  • P2O5-Al2O3 Catalyzed One Pot Acetylation, Benzylidene Acetal Protection and Benzylidene Removal of Sugar Derivatives
    作者:Anjali Sharma、Rajib Panchadhayee
    DOI:10.14233/ajchem.2023.27842
    日期:——

    An environment-friendly, simple and efficient one-pot acetylation and benzylidene acetal formation procedure has been introduced for the synthesis of sugar derivatives using P2O5-Al2O3 as a solid acid catalyst under solvent-free condition at room temperature, with excellent overall yield. This benzylidene acetal has been deprotected using the same reagent but in a moist condition.
