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.

Sulfur atom configuration of sulfinyl galactofuranosides determines different reactivities in glycosylation reactions

Sulfinyl β-D-galactofuranosides 3(R,S) and 9(R,S) were used as new hexofuranosyl donors in glycosylation reactions. Activation by trifluoromethanesulfonic anhydride involved different reaction pathways depending on the stereochemistry at the sulfur atom. Experimental results underlined a more suitable reactivity of 3(R) and 9(R) versus 3(S) and 9(S), respectively, for the synthesis of β-D-galactofuranosides. (C) 2000 Elsevier Science Ltd.
