Abstract Methyl α D-fructofuranoside was transformed regioselectively into the corresponding 6-S-thioacetate in one step by use of the thio-Mitsunobu reaction. Reaction of the trimesylate derived from this thioacetate with sodium hydrogen carbonate led to the thietanosugar methyl 4,6-anhydro-1,3-di-O-mesyl-4-thio-α -D-tagatofuranoside. Methyl β -D-fructofuranoside gave the corresponding 6-S-thioacetate
