• Synthesis of 5-Thio-<scp>l</scp>-fucose-Containing Disaccharides, as Sequence-Specific Inhibitors, and 2‘-Fucosyllactose, as a Substrate of α-<scp>l</scp>-Fucosidases
  作者：Masayuki Izumi、Osamu Tsuruta、Satoru Harayama、Hironobu Hashimoto

  DOI：10.1021/jo961725h

  日期：1997.2.1

  Four 5-thio-L-fucose-containing disaccharides having alpha(1-->6), alpha(1-->3), alpha(1-->4)GlcNAc, and alpha(1-->2-Gal linkages (compounds 1-4, respectively) were synthesized as potential alpha-L-fucosidase inhibitors. The glycosylation reactions using 2,3,4-tri-O-acetyl-5-thio-L-fucopyranosyl trichloroacetimidate as a glycosyl donor and BF3 . OEt(2) as a catalyst gave mainly alpha-linked disaccharides. Only alpha(1-->2)-linked disaccharide 4 showed inhibitory activity (K-i = 0.21 mM) against Bacillus alpha-L-fucosidase which hydrolyzes the Fuc alpha(1-->2) linkage specifically. The results suggested that sequence specificity of an enzyme could be estimated from the inhibitory activities of the compounds 1-4. In contrast, every disaccharide showed inhibitory activity (K-i = 30-91 mu M) against bovine epididymis alpha-L-fucosidase.
• A novel 5-thioglycosylation method with 1,5-dithioglycosyl donors: relevance to exo- versus endocyclic activation
  作者：Hideya Yuasa、Osamu Tsuruta、Hironobu Hashimoto

  日期：2007.11

  5-Thioglucosylation of a 1,6-anhydro-2-azido-2-deoxy-beta-D-glucopyranose derivative was carried out with various 1,5-dithioglucosyl donors. The use of per-O-acetyl donors resulted in poor yields of an alpha-disaccharide. On the other hand, per-O-benzyl donors selectively gave an alpha-disaccharide in good to excellent yields regardless of the anomeric configuration of the donors. To study the relevance of the glycosylation results to the pre-equilibrium of exo- versus endocyclic sulfide activation, the relative nucleophilicities of exo- and endocyclic sulfides were estimated from the regioselectivities in the electrophilic oxidation of the per-O-benzyl donors with m-chloroperbenzoic acid. The results obeyed stereoelectronic effects and the endocyclic sulfides were more nucleophilic than the exocyclic sulfides for both anomers of per-O-benzyl-1,5-dithioglucosyl donors, the relative nucleophilicities of the endocyclic over exocyclic sulfides being 67% and 100%, respectively, for the alpha- and beta-anomers. The results of the glycosidation and oxidation suggest that the glycosidation proceeded through an exocyclic cleavage mechanism despite the preferential endocyclic activation of 1,5-dithioglucosides.
