Synthesis of Anomeric Methyl Fructofuranosides and Their Separation on an Ion-exchange Resin  Erkki Nurminen, Päivi Poijärvi, Katja Koskua, and Jari Hovinen
Treatment of d-fructose with methanol in the presence of acid as a catalyst gives a mixture of methyl--d-fructopyranoside, methyl-a-D-fructofuranoside, and methyl--d- fructofuranoside, which are separated on an ion exchange column and characterized polarimetrically.
