  Synthesis of Di- and Trisaccharides Comprising D-Fructopyranose with β2 → 1 Glycosidic Linkage Using β-D-Fructopyranosyl Fluoride as the Fructosyl Donor

  摘要：

  D-Fructose was converted into a stable, suitably protected fructosyl donor for iterative glycosylation, i.e., 1-O-acetyl-3,4,5-tri-O-benzyl-beta-D-fructoyranosyl fluoride and a fructosyl acceptor, methoxymethyl 3,4,5-tri-O-benzyl-beta-D-fructopyranoside in good yields. Glycosylation of the both substrates provided di- and trisaccharides comprising beta-D-fructopyranose with beta (2 -> 1)-interglycosidic linkage.
