The first synthesis of hexasaccharide 1 representing a repeat unit of a polysaccharide specific to the vegetative cellwall of Bacillus anthracis is reported. The synthetic hexasaccharide is equipped with an n-pentenyl handle at the reducing terminus to allow for further functionalization. Key transformations during the synthesis are the conversion of a glucose into a mannosazide residue, a (2+2) coupling
