Indeed, due to the high polarity and the functional richness of sugars, many different structures can be targeted, with a wide range of physicochemical properties, either for large scale products of industrial interest, or for fine applications at the chemistry-biology interface. Among carbohydrates arising from agricultural resources, sucrose is especially interesting because of its very large production scale in the world (ca. 160Mt/year, ca. 20Mt/year of which in the European Community). Here, we describe the research accomplished in our group dealing with the synthesis and the study of the properties of amphiphilic derivatives prepared from sucrose as well as from another very available disaccharide, isomaltulose.

A series of mono-, di-, or triazido polyhydroxylated systems are described.

Melezitose led to esters with preferential substitution at primary positions following the order of reactivity 6 00 > 6 > 6 0 . Raffinose proved to be very reluctant toward ester formation in these conditions, leading mainly to the new 3 00 ,6 00 -anhydroraffinose.
