    of the triol 9, leading in each sequence to the branched tetrasaccharide, beta-D-GlcpNAc-(1----3)-[beta-D-GlcpNAc-(1----6)]-beta-D-Galp-(1----4)- beta-D-GlcOMe. Similar glycosylations performed with 3,6-di-O-acetyl-2-deoxy-2-phthalimido-4-O-(2,3,4, 6-tetra-O-acetyl-beta-D-galactopyranosyl)-beta-D-glucopyranosyl trichloroacetimidate afforded the branched hexasaccharide beta-D-Galp-(1----4)-beta-D-Glc

    Abstract N -Phthaloyl derivatives of 2-acetamido-2-deoxy- d -glucose having OH-1 free treated with trichloroacetonitrile and sodium hydride gave the corresponding O -(β- d -glycosyl)trichloroacetimidates which in the presence of diethyl ether·borontrifluoride, led selectively with alcohols to β- d -glycosides. This procedure was applied to the synthesis of oligosaccharides from the core region of mucine-type

  • Rapid Access to an Orthogonally Protected Lewis X Derivative: An Important Building Block for Synthesis of Lewis Antigens
    作者:Masashi Ohmae、Junko Takada、Hiroaki Murakami、Shunsaku Kimura
    DOI:10.1246/cl.2011.438
    日期:2011.5.5
    A novel Lewis X derivative of 1 with an orthogonal set of protecting groups was systematically prepared. Efficient use of the protecting groups for the amino and the hydroxy groups in lactosamine enabled formation of the diol derivative at C3 and C2′. Glycosidation of 1-thio-l-fucoside donor with the diol derivative progressed preferably at the C3 hydroxy group, resulting in prior production of 1. Compound 1 is a key building block toward easy assemblies of Lewis X-related carbohydrate epitopes.
