  The Synthesis of an O,C-Trisaccharide: The O,C-Analog of Methyl 4′-O-β-d-glucopyranosylgentiobioside

  摘要：

  The synthesis of an O,C-trisaccharide, namely methyl O-beta-D-glucopyranosyl-(1-->4)-C-beta-D-glucop glucopyranoside, was achieved in 14 steps by way of the nitro-aldol coupling of hepta-O-acetyl-beta-cellobiosylnitromethane and methyl 6-aldehydo-2,3,4-tri-O-benzyl-alpha-D-gluco-1,5-pyranoside, followed by the elaboration of the coupling product. The resulting O,C-trisaccharide constitutes a potential inhibitor of the beta glucanases of the cellulase family. The perbenzylated derivative of cellobiosyl nitromethane was also prepared. Both disaccharide-C-glycosides constitute useful starting materials for the preparation of higher mixed O,C-oligosaccharides. (C) 1999 Elsevier Science Ltd. All rights reserved.
