A New Approach to a Disaccharidic Hapten Containing a Galactofuranosyl Entity.

A short synthetic entry into the disaccharidic hapten β-D-Galf-(1→3)-α-D-Manp-O(CH2)8CO2Me containing a galactofuranosyl entity at the non-reducing part is described. The synthetic scheme was designed in such a way that each required building block could be obtained by minimizing the number of chemical and purification steps. Indeed, compound 8 was obtained according to a four step–one pot preparation.
