    Synthesis of α-d-Galp-(1→3)-β-d-Galf-(1→3)-d-Man, a Terminal Trisaccharide of Leishmania Type-2 Glycoinositolphospholipids
    摘要:
    The synthesis of alpha-D-Galp-(1-->3)-beta-D-Galf-(1-->3)-D-Man, present in the type-2 glycoinositolphospholipids and in the core of the lipophosphoglycan of Leishmania, is described. The glycosyl aldonolactone approach, followed by reduction of the lactone with diisoamylborane, was utilized for the introduction of the internal galactofuranosyl unit and the trichloroacetimidate method for the O-glycosidation reaction. A high-yield synthesis of the O-D-Galf-(1-->3)-D-Man unit, also present in the lipopeptidophosphoglycan of Trypanosoma cruzi, is reported.

    The synthesis of free β-d-Galp-(13)-β-d-Galp-(1→6)-[β-d-Galf-(1→4)]-d-GlcNAc and the corresponding alditol which has been previously isolated by reductive β-elimination of Trypanosoma cruzi glycoproteins are described. A convergent route was envisioned by condensing an acceptor derivative of β-d-Galf-(1→4)-d-GlcNAc with a donor derivative of β-d-Galp-(13)-d-Galp. The trichloroacetimidate method, as
