  • 2-<i>O</i>-<i>N</i>-Benzylcarbamoyl as a Protecting Group To Promote β-Selective Glycosylation and Its Applications in the Stereoselective Synthesis of Oligosaccharides
    作者:Yin-Jen Lu、Yen-Hsun Lai、You-Yu Lin、Yi-Chi Wang、Pi-Hui Liang
    DOI:10.1021/acs.joc.8b00047
    日期:2018.4.6
    This study examines the utility of the N-benzylcarbamoyl (BnCar) protecting group in glycosylation reactions of the parent O-2 protected carbohydrate donor. It was found that the BnCar group imparted exclusively β-selectivity with primary and secondary alcohols. A mechanistic study revealed the activated intermediate to be the glycosyl triflate in a skew conformation, which results in β-selective glycosylation
    这项研究研究了N-苄基甲酰基(BnCar)保护基在亲本O -2保护的碳水化合物供体的糖基化反应中的作用。发现BnCar基团仅赋予伯醇和仲醇β-选择性。一项机理研究表明,活化的中间体为偏构型的三氟甲磺酸糖基酯,可通过类似S N 2的途径导致β选择性糖基化。BnCar基团可以使用亚硝酸四丁容易地裂解,而不会影响酯和醚保护基。综上所述,这些结果表明BnCar可用于合成复杂的低聚糖,这项工作需要对各种保护基进行精细的化学区分。
  • Total Synthesis of a Glycoglycerolipid from<i>Meiothermus taiwanensis</i>through a One-Pot Glycosylation Reaction and Exploration of its Immunological Properties
    作者:Bhaswati Ghosh、Yen-Hsun Lai、Yu-Yin Shih、Tapan Kumar Pradhan、Chun-Hung Lin、Kwok-Kong Tony Mong
    DOI:10.1002/asia.201300933
    日期:2013.12
    The total synthesis of a glycoglycerolipid isolate of Meiothermus taiwanensis and its truncated structural analogues is reported. Our synthesis employed DMF‐modulated and low‐concentration glycosylation reactions for the construction of α‐ and β‐glycosidic bonds in the absence of participating protecting groups. Further simplification of the synthesis was achieved by employing a low‐concentration one‐pot
    报道了台湾Meiothermus taiwanensis的糖甘油脂分离物及其截短的结构类似物的总合成。我们的合成方法是在没有保护基团参与的情况下,采用DMF调节的低浓度糖基化反应来构建α-和β-糖苷键。通过采用低浓度单锅糖基化程序,进一步简化了合成过程。初步的免疫学研究表明,一种截短的结构类似物抑制了THP-1单核细胞的细胞因子产生。
  • Iterative α-Glycosylation Strategy for 2-Deoxy- and 2,6-Dideoxysugars: Application to the One-Pot Synthesis of Deoxysugar-Containing Oligosaccharides
    作者:Jiun-Han Chen、Jyh-Herng Ruei、Kwok-Kong Tony Mong
    DOI:10.1002/ejoc.201400006
    日期:2014.3
    This paper describes the development of an iterative and α-selective glycosylation method for 2-deoxyglycosyl and 2,6-dideoxythioglycoside donors based on the DMF modulation concept. We used NMR spectroscopy to probe the 2-deoxyglycosyl imidinium intermediate and elucidated the conditions to decrease the formation of glycal and thus to increase the reaction yields. Further elaboration of the glycosylation
    本文描述了基于 DMF 调制概念的 2-脱氧糖基和 2,6-二脱氧糖苷供体的迭代和 α-选择性糖基化方法的开发。我们使用 NMR 光谱来探测 2-脱氧糖基亚胺鎓中间体,并阐明了减少糖醛形成从而提高反应产率的条件。糖基化方法的进一步阐述为含 2-脱氧和 2,6-双脱氧糖苷的低聚糖的迭代一锅法合成打开了大门。
  • Neighboring-Group Participation by C-2 Ether Functions in Glycosylations Directed by Nitrile Solvents
    作者:Chin-Sheng Chao、Ching-Yu Lin、Shaheen Mulani、Wei-Cheng Hung、Kwok-kong Tony Mong
    DOI:10.1002/chem.201100732
    日期:2011.10.17
    Ether‐protecting functions at C‐2 hydroxy groups have been found to play participating roles in glycosylations when the reactions are conducted in nitrile solvent mixtures. The participation mechanism is based on intramolecular interaction between the lone electron pair of the oxygen atom of the C‐2 ether function and the nitrile molecule when they are positioned in a cis configuration. A 1,2‐cis glycosyl
    当在腈溶剂混合物中进行反应时,已发现在C-2羟基处的醚保护功能在糖基化中起参与作用。参与机制基于C-2醚功能的氧原子的孤电子对和腈分子以顺式排列时的分子内相互作用。形成一个1,2-顺式糖基恶唑啉鎓中间体。这种参与,再加上糖基供体的异头作用,赋予糖基化较高的1,2-反式选择性。该概念的进一步应用导致了α-(1→5)-阿拉伯低聚物的高效制备。
  • Iterative One-Pot α-Glycosylation Strategy: Application to Oligosaccharide Synthesis
    作者:Chih-Yueh Ivan Liu、Shaheen Mulani、Kwok-Kong Tony Mong
    DOI:10.1002/adsc.201200396
    日期:2012.11.26
    three iterative one-pot α-glycosylation methods, i.e., one-pot (α,α)-, one-pot (β,α)-, and one-pot (α,β)-glycosylations, were developed. These methods are applicable to a range of thioglycosyl donors, confer stereocontrol in α-/β-glycosidic bond formation, and thus provide for rapid access to oligosaccharides with various permutations of anomeric configurations. The utility of these one-pot glycosylation
    基于二甲基甲酰胺(DMF)调节和邻近基团参与的组合使用,三种迭代的一锅法α-糖基化方法,即一锅法(α,α)-,一锅法(β,α)-和一种锅(α,β)糖基化。这些方法适用于一系列糖基供体,赋予α-/β-糖苷键形成立体控制,因此可快速进入具有异头构型各种排列的寡糖。这些一锅式糖基化方法的实用性在八个非天然和天然寡糖靶标的合成中得到了证明,其中包括核心1丝氨酸缀合物,核心8丝氨酸缀合物,D-Gal-α(13)-D-Glc-肺炎链球菌细胞壁成分的α(13)-L-Rha三糖单元N连接的聚糖前体的D-Glc-α(12)-D-Glc-α(13)-D-Glc三糖末端。这些低聚糖的端基异构构型的确认通过1 H,13 C,13 C-非质子去耦和异核相关2D NMR实验证明。说明了所选寡糖靶标的整体脱保护。
