  Formation of orthoester-linked d-arabinofuranose oligosaccharides and their isomerization into the corresponding glycosides

  摘要：

  Orthoester-linked D-arabinofuranose oligosaccharides were isolated in high yield for the first time via glycosylations with 2-O-chloroacetyl-substituded D-arabinofuranose thioglycosides promoted by NIS-AgOTf in the presence of 4 A molecular sieves in CH2Cl2. These orthoesters can be rearranged into the isomeric glycosidically-linked oligosaccharides by treatment with TMSOTf in CH2Cl2, or in situ by extension of the reaction time. (C) 2011 Elsevier Ltd.

  Ring opening of acylated β-d-arabinofuranose 1,2,5-orthobenzoates with nucleophiles allows access to novel selectively-protected arabinofuranose building blocks

  摘要：

  beta-D-Arabinofuranose 1,2,5-orthobenzoates with 3-O-acetyl, 3-O-benzoyl, and 3-O-chloroacetyl groups were prepared in an efficient manner starting from readily available crystalline methyl 2,3,5-tri-O-benzoyl-alpha-D-arabinofuranoside, and ring-opening reactions of these compounds with O- and S-nucleophiles were studied. Optimized conditions leading to the formation of the respective monosaccharide adducts (up to 96% isolated yields) and to alpha-(1 -> 5)-linked disaccharide thioglycosides with 5'-OH unprotected (up to 30% isolated yields) were found. Basing on these results, a novel approach for effective differentiation of 3,5-diol system and 2-hydroxy group in arabinofuranose thioglycosides was proposed. The selectively protected derivatives prepared are valuable building blocks for the assembly of linear and branched oligoarabinofuranosides. (C) 2010 Elsevier Ltd. All rights reserved.
