  Synthesis and galectin-binding activities of mercaptododecyl glycosides containing a terminal β-galactosyl group

  摘要：

  Mercaptododecyl glycosides containing a terminal beta-galactosyl group were prepared from D-galactose or from D-lactose via hexa-O-acetyl-lactal (10) as a key intermediate. Interactions of these glycolipids (5 kinds) and galectins (beta-galactoside binding lectins, 6 species) were evaluated by surface plasmon resonance (SPR) method. High binding responses were observed for the lactoside, 2-deoxy-lactoside, and lactosaminide with some galectins (Gal-3, -4, -8), whereas the galactoside and 2,3-dideoxy-lactoside showed low binding activities.

  of alcohols has been developed using O-acetylated glycals, trichloroethoxysulfonamide, and iodosobenzene. This one-pot amidoglycosylation was applied to a variety of primary and secondary alcohols to afford the beta-O-glycosides with acceptable yields up to 84%. The reaction would proceed via stereoselective intermolecular aziridination of the glycal from the alpha-face followed by SN2 reaction with

  使用O-乙酰基化的糖，三氯乙氧基磺酰胺和碘代苯，已经开发出了区域和立体控制的铑（II）催化的醇酰胺糖基化反应。将这种一锅式酰胺基糖基化反应应用于各种伯醇和仲醇，以高达84％的可接受收率得到β-O-糖苷。该反应将通过α面的糖的立体选择性分子间叠氮化进行，然后与β面的C-1处的醇进行SN2反应，仅得到1,2：2,3-二-反式取代的异构体。
