摘要:
Starting from L-arabinose and methyl beta-D-galactopyranoside, methyl 2,3,4-tri-O-benzyl-6-O-[2,4,6-tri-O-benzoyl-3-O-(2,3,5 -tri-O-benzoyl-alpha-L-arabinofuranosyl)-beta-D -galactopyranosyl]-beta-D-galactopyranoside 10 has been synthesized. Removal of protecting groups gave the methyl glycoside 12 of a trisaccharide representative of a repeating unit of arabinogalactan (AGP) polysaccharides.
