Synthesis of a hexasaccharide that relates to the arabinogalactan epitope

A hexasaccharide derivative of the arabinogalactan epitope, methyl β-D-galactopyranosyl-(1 → 6)-[α-L-arabinofuranosyl-(1 → 3)]-β-D-galactopyranosyl-(1 → 6)-β-D-galactopyranosyl-(1 → 6)-[α-L-arabinofuranosyl-(1 → 3)]-α-D-galactopyranoside, was synthesized efficiently using a 3 + 3 strategy. The key step is the preparation of the trisaccharide donor, isopropyl 2,3,4,6-tetra-O-benzoyl-β-D-galactopyranosyl-(1 → 6)-[2,3,5-tri-O-benzoyl-α-L-arabinofuranosyl-(1 → 3)]-2,4-di-O-benzoyl-1-thio-β-D-galactopyranoside, from isopropyl 1-thio-β-D-galactopyranoside using a one-pot synthesis of a 3,6-differentially protected building block.
