The epoxide ring of methyl 3,4-anhydro-β-d-tagatofuranoside is opened byattack of nucleophiles at C-4 to yield derivatives of D-fructose. Treatment of 2,3-O-isopropylidene-1,6-di-Op-tolylsulfonyl-β-d-fructofuranose with sulfuryl chloride resulted in attack at C-6, not C-4. 2,3-O-Isopropylidene-1,6-di-O-p-tolylsulfonyl-β-d-tagatofuranose behaved normally with this reagent. Methyl 4-deoxy-β-d-threo-hexulofuranoside was not hydrolysed by invertase.
