    使用光氧化还原催化和氢原子转移从酰化吡喃糖苷合成酮脱氧糖
    摘要:
    光氧化还原催化剂、氢原子转移介质和氢键受体助催化剂的联合作用已被用于实现吡喃糖苷衍生酯向酮脱氧糖的转化。酰基的位置决定了脱氧位点,从而能够制备 2-脱氧和 4-脱氧酮糖衍生物。这些产品是生物活性次级代谢产物的稀有糖成分的有用前体。计算研究与自由基裂解酶机制一致,其中关键消除步骤通过自由基中间体中的 1,2-酰氧基迁移进行。

    Induction of a Preferred Sense of Twist in Flexible Diphenyls by Carbohydrate Scaffolds. Synthesis of Two “Naked” Ellagitannin Analogous
    摘要:
    The synthesis of "naked" ellagitannin analogues 1 and 2, having a preferred sense of twist of the diphenyl moiety, with a rhamnose and a glucose template, is reported. A clear induction in the chirality of the diphenyl moiety, mediated through a 10-membered ring via ester linkages, was observed. The chiral scaffold of glucose (diequatorial 2,3-hydroxyl groups) exerts a remarkable stronger atropdiastereoselective effect onto the diphenoyl group than the rhamnose ring (axial-equatorial 2,3-hydroxyl groups), according to the Schmidt-Haslam hypothesis.

  • Asymmetric synthesis of methyl 6-deoxy-3-O-methyl-α-l-mannopyranoside from a non-carbohydrate precursor
    作者:Wenting Du、Yongzhou Hu
    DOI:10.1016/j.carres.2006.01.019
    日期:2006.5
    A novel method is reported for preparing methyl 6-deoxy-3-O-methyl-alpha-L-mannopyranoside (1) by asymmetric synthesis, using 2-acetylfuran (2), a non-chiral simple molecule, as the starting material and achieving high yields via (S)-1-(2-furyl)ethanol and (S)-1-(2,5-dihydro-2,5-dimethoxy-2-furyl)ethanol.

  • Acyl Group Migration in Pyranosides as Studied by Experimental and Computational Methods

    have studied the acyl migration in different monosaccharides using five different acyl groups by a combination of experimental, kinetic and theoretical tools. The results show that the anomeric configuration in the monosaccharide has a major influence on the migration rate, together with the relative configurations of the other hydroxyl groups and the nature of the migrating acyl group.

    酰基迁移影响所有含有游离羟基的酰化有机化合物,特别是碳水化合物的合成、分离、操作和纯化。虽然已经报道了一些关于不同缓冲液中迁移现象的孤立研究,但缺乏对类似条件下不同单糖整体迁移过程的全面了解。在这里,我们结合实验、动力学和理论工具,使用五种不同的酰基研究了不同单糖中的酰基迁移。结果表明,单糖中的异头构型与其他羟基的相对构型和迁移酰基的性质一起对迁移速率有重大影响。全机械模型,基于计算,

  • Synthesis of Ketodeoxysugars from Acylated Pyranosides Using Photoredox Catalysis and Hydrogen Atom Transfer

    DOI:10.1021/acscatal.1c03050
    日期:2021.9.3
    The combined action of a photoredox catalyst, a hydrogen atom transfer mediator, and a hydrogen bond acceptor cocatalyst has been used to achieve the transformation of pyranoside-derived esters into ketodeoxysugars. The position of the acyl group dictates the site of deoxygenation, enabling the preparation of 2-deoxy- and 4-deoxyketosugar derivatives. The products are useful precursors to rare sugar
