  • Sweet (hetero)aromatics: glycosylated templates for the construction of saccharide mimetics
    作者:Christine Wiebe、Claudine Schlemmer、Stefan Weck、Till Opatz
    DOI:10.1039/c1cc13078a
    日期:——
    Mono- and diglycosylated aromatics and heteroaromatics may serve as building blocks for the construction of metabolically stable mimetics of oligosaccharides. Methods for their preparation from monosaccharidic precursors by direct C-glycosylation, dipolar cycloaddition or Larock cyclization are described.

  • Synthesis of β-analogues of C-mannosyltryptophan, a novel C-glycosylamino acid found in proteins
    作者:Toshio Nishikawa、Yuya Koide、Akira Kanakubo、Hiroshi Yoshimura、Minoru Isobe
    DOI:10.1039/b516282c

    α-C-Mannosyltryptophan (α-C-Man-Trp) has been found to be a novel post-translational modification of tryptophan found from some biologically important glycoproteins. In order to analyze the biological functions of α-C-Man-Trp, we have developed an efficient synthetic strategy for α-C-Man-Trp and its glucose and galactose analogues, starting from α-C-glycosidation of the corresponding hexapyranoside derivatives with tinacetylene. According to the synthetic routes, we describe here syntheses of β-anomers of C-Man-Trp, and its glucose and galactose analogues from the corresponding β-C-glycosylacetylenes. During this study, we have developed a highly stereocontrolled synthesis of β-C-mannosylacetylene that is required for the synthesis of β-C-Man-Trp, while the precedented method gave an anomeric mixture of the C-mannosylacetylene. The synthetic C-Man-Trp and its analogues were analyzed by HPLC.
    α-C-甘露糖基色酸(α-C-Man-Trp)被发现是一种新的色酸翻译后修饰,存在于一些生物重要的糖蛋白中。为了分析α-C-Man-Trp的生物功能,我们开发了一种高效的合成策略,用于α-C-Man-Trp及其葡萄糖和半乳糖类似物,从对应的六糖派拉诺糖衍生物乙炔的α-C-糖苷化反应开始。根据合成路线,我们在此描述了从相应的β-C-糖苷乙炔生物合成β-异构体的C-Man-Trp及其葡萄糖和半乳糖类似物。在这项研究中,我们开发了一种高度立体选择性合成β-C-甘露糖乙炔的方法,这是合成β-C-Man-Trp所必需的,而先前的方法则给出了C-甘露糖乙炔的异构体混合物。合成的C-Man-Trp及其类似物通过高效液相色谱(HPLC)进行了分析。

  • Unexpected formation of glycals upon attempted C-alkylation of protected glycosylacetylenes
    作者:Tedd M. Davis、Todd L. Lowary

    4-trideoxy-D-arabino-oct-3-en-1-yn itol (glycal acetylene, 3) as the major product. Additional studies showed that 3 is also produced from two isomers of 1 with alpha-D-mannosyl and beta-D-glucosyl stereochemistry, but in lower yields. Furthermore, substrates in which the acetylene moiety is replaced by either a methyl or phenyl group do not produce a glycal product under these conditions. Finally,

  • First synthesis of 1,2,3-triazolo-linked (1,6)-α-<scp>d</scp>-oligomannoses (triazolomannoses) by iterative Cu(<scp>i</scp>)-catalyzed alkyne–azide cycloaddition
    作者:Pavel Cheshev、Alberto Marra、Alessandro Dondoni

    日期:——
    The iterative copper(I)-catalyzed cycloaddition (rt or microwave) between an ethynyl alpha-C-mannoside and alkyl 6-azido-alpha-C-mannoside derivatives was suited to the (1,6)-ligation between alpha-D-mannose units through 1,4-disubstituted triazole bridges, thus resulting in the formation of linear oligomers (80-90% yield) with alternating triazole and mannose fragments up to a triazolo-pentamannose
