Inulin triacetate

In 1952, Wolfrom and Hilton demonstrated that L-sorbose was also capable of forming dimeric dianhydrides,22 and they postulated sorbofuranosyl and pyra-nosyl cationic intermediates. In 1955, Boggs and Smith23 postulated a fructofu-ranosyl cationic intermediate in the formation of per-O-acetyl ot-D-Fru/-1,2 2,l -p-D-Fru/[di-D-fructose anhydride I (5)] from inulin triacetate. They indicated that three adjacent P-2,l -linked fructofuranosyl units would be required for formation of the dianhydride. 

Sucrose was first chemically synthesized using Brigl s anhydride and 1,3,4,6-tetra-O-acetyl-P-D-fructofuranose (the latter prepared by reacting inulin triacetate with HBr in glacial acetic acid [83] (reaction 4.69).
