  Synthesis of D-Fructofuranosylpurine Nucleosides

  摘要：

  The Mitsunobu reaction has been applied to the formation of purine nucleosides of D-fructofuranose. The use of O-benzyl protection results in a predominance of the beta-configuration in these novel compounds and both alpha- and beta-D-fructofuranosyladenine are obtained in stereochemically pure form.

  Several partially benzylated mono-, di-, and trisaccharides having an anomeric hydroxyl group were successfully prepared by selective cleavage of the beta-fructofuranosidic linkage in fully benzylated sucrose and sucrose-related oligosaccharides derived from lactosucrose, raffinose, melezitose, stachyose, and nystose under acidic conditions using 1:10 75% aqueous sulfuric acid-dioxane at room temperature
