Epimerisation and subsequent functionalization at C-5 of D-fructopyranose derivatives under Mitsunobu and Garegg's conditions provided efficient access to 5-thio-D-fructose (2) as well as to 5-azido-5-deoxy-1,2-O-isopropylidene-beta -D-fructopyranose (19), a known precursor to 2,5-deoxy-2,5-imino-D-mannitol (3). The interaction of 2 with the D-fructose transporter GLUTS, was found to be weaker than that of D-fructose, a result that suggests involvement of the ring oxygen atom in the recognition of D-fructose by GLUTS.
