Synthesis of β-D-Galp-(1→3)-β-D-Galp-(1→6)-[β-D-Galf- (1→4)]-D-GlcNAc, a tetrasaccharide component of mucins of Trypanosoma cruzi
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-G...
