Patent ID: 7109182

Claim:
A process for preparing a synthetic oligomannoside, wherein at least one functional group of the synthetic oligomannoside is a connector comprising a carboxylic acid functional group or a C 1 to C 10 alkyl, the synthetic oligomannoside being devoid of cellular components and homologous to a wall oligomannoside of an infectious organism or pathogen, from monosaccharides or disaccharides by condensation of protected dimannosides comprising: a) preparing diblocks in which: at least one of two blocks is the intermediary block in which free hydroxyl functional groups of the monosaccharides are protected by one or more, identical or different protector groups, except for a hydroxyl functional group necessary for condensation with another diblock which is activated by a starting group, and one of the two blocks is a terminal block in which free hydroxyl functional groups of the monosaccharides are protected by one or more, identical or different protector groups, except for a hydroxyl functional group necessary for condensation with another diblock, and optionally a hydroxyl functional group protected by a binding group for attachment of the oligomannoside on a support, b) condensing said diblocks, and c) deprotecting resulting oligomannoside.
