    摘要:
    A flavinium catalyst, in conjunction with hydrogen peroxide as stoichiometric oxidant, allowed the aqueous conversion of non-protected thioglycosides into the corresponding glycosyl sulfoxides. These glycosyl sulfoxides displayed only very weak inhibitory activity against corresponding glycosidases. (C) 2015 Elsevier Ltd. All rights reserved.

  • Galactosylation by use of β-galactosidase: Chemo-enzymatic syntheses of di- and trisaccharides
    作者:Wolfgang H. Binder、Hanspeter Kählig、Walther Schmid

    of various galactose containing disaccharides has been achieved by utilizing the transgalactosylation potential of β-galactosidase from Aspergillus oryzae. Thus, using p- nitrophenyl-β-D-galactoside 1 as galactosyl donor, thio-glucosides 2a-c, thio-galactosides 5a, 5b and pent-4-enyl-glucoside 2d have proved to be useful acceptors for the enzyme catalyzed disaccharide formation. We further demonstrated

    Different ethyl 1-thio-β-D-disaccharides have been synthesised by transgalactosylation using the β-galactosidase from Bacillus circulans as biocatalyst. This β-galactosidase shows mainly a β-1–4 specificity in the galactosyl transfer. Gal-β-(1–4)-O-β-D-GlcSEt 15 was obtained in 36% yield, Gal-β-(1ndash;4)-O-α-D-GlcSEt 19 in 30% yield, Gal-β-(1–4)-O-β-D-GalSEt 17 in 60% yield, Gal-β-(1–4)-O-β-D-GalNAcSEt
