Abstract: Starting from D-galactose, and D-mannose a trisaccharide namely 2-(trimethylsilyl)ethyl-2,3-di-<i>O</i>-benzoyl-4,6-<i>O</i>-[(<i>R</i>)-1-methoxycarbonylethylidene]-<img src='/image/spc_char/beta.gif' border=0>-D-galactopyranosyl-(1→4)-2, 3, 6-tri-<i>O</i>-benzyl-b-d-mannopyranosyl-(1→4)-2,6-di-<i>O</i>-ben­zyl-3-<i>O</i>-(4-methoxybenzyl)-<img src='/image/spc_char/beta.gif' border=0>-D-galactopyranoside has been synthesized. Deprotection of the blocking functionality affords a deblocked trisaccharide, 2-(trimethylsilyl)ethyl-4,6-<i>O</i>-[(<i>R</i>)-1-methoxycarbonylethylidene]-<img src='/image/spc_char/beta.gif' border=0>-D-galactopyranosyl-(1→4)-<img src='/image/spc_char/beta.gif' border=0>-D-mannopyranosyl-(1→4)-<img src='/image/spc_char/beta.gif' border=0>-D-galactopyranoside which is a part of the repeating unit of the <i>O</i>-antigen from <i>Shigella dysenteriae</i> type 9.
