  • Synthesis of Two Tetra- and Four Pentasaccharide Fragments of<i>Shigella flexneri</i>Serotypes 3a and X O-Antigens from a Common Tetrasaccharide Intermediate
    作者:Julien Boutet、Laurence A. Mulard

    日期:2008.11
    Ac→2]-α-L-Rhap-(1→3)-β-D-GlcpNAc-(1→}n ((E)ABAcCD)n polymer were synthesized as their propyl glycosides by use of a common fully protected (E)ABAcC intermediate (9). Tetrasaccharide 9 derived from the condensation of an EA donor and a BAcC acceptor. Partial and full deprotection gave free tetrasaccharides (E)ABAcC and (E)ABC, respectively. Alternatively, 9 was converted into a trichloroacetimidate

  • Efficient route to orthogonally protected precursors of 2-acylamino-2-deoxy-3-O-substituted-β-d-glucopyranose derivatives and use thereof
    作者:Julien Boutet、Tae Hee Kim、Catherine Guerreiro、Laurence A. Mulard
    DOI:10.1016/j.tetlet.2008.06.052
    日期:2008.9
    An efficient route to two 3-O-acyl-2-deoxy-4,6-O-isopropylidene-2-trichloroacetamido-D-glucopyranosyl trichloroacetimidate donors is reported. As demonstrated for the 3-O-acetyl derivative, these building blocks are exquisite beta-D-glucosamine donors when reacted either with simple alcohols or with complex oligosaccharides. Besides, their protection pattern is compatible with selective deprotection and subsequent chain elongation at O-3 of the newly incorporated glucosamine residue. (C) 2008 Elsevier Ltd.
