The synthesis of free β-d-Galp-(1→3)-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-(1→3)-d-Galp. The trichloroacetimidatemethod, as
