    Synthesis of monodeoxy and mono-O-methyl congeners of methyl β-d-mannopyranosyl-(1→2)-β-d-mannopyranoside for epitope mapping of anti-Candida albicans antibodies
    摘要:
    A panel of six complementary monodeoxy and mono-O-methyl congeners of methyl beta-D-mannopyranosyl-(1 -> 2)-beta-D-mannopyranoside (1) were synthesized by stereoselective glycosylation of monodeoxy and mono-O-methyl monosaccharide acceptors with a 2-O-acetyl-glucosyl trichloroacetimidate donor, followed by a two-step oxidation-reduction sequence at C-2'. The beta-manno configuration of the final deprotected congeners 2-7 was confirmed by measurement of (1)J(C1.H1) heteronuclear and (3)J(1'.2), homonuclear coupling constants. These disaccharide derivatives will be used to map the epitope recognized bit a protective anti-Candida albicans monoclonal antibody C3.1 (IgG3) and to determine its key polar contacts with the binding site.

    摘要:
    2- [二甲基(2-萘基甲基)甲硅烷基]乙氧基碳酸酯(NSEC)是一种新颖的保护基,可掩盖羟基。NSECCl分三步可从氯二甲基乙烯基硅烷和2-(溴甲基)萘获得。在目前碳水化合物化学中使用的大多数保护基团的存在下,可以轻松,快速地进行NSEC基团的引入和去除。NSEC的去除可以在各种醚和酯保护基存在的条件下,在温和的条件下进行。另外,NSEC基团对使用糖基磷酸酯的糖基化条件稳定。包含NSEC的二糖18的合成已经完成。

    study of various metal trifluoromethanesulfonates as efficient catalysts in the regioselective reductive ring opening of benzylidene acetals is described, including the effects of solvents, reducing agents, and temperature. These catalysts are found to be effective in cleaving the 4,6‐O‐acetal rings of hexopyranosides at either O4 or O6, respectively. When used in conjunction with a 1 M solution of
