摘要：

alpha-D-Fructopyranose beta-D-fructopyranose-1,2':2,1'-dianhydride has been stereoselectively synthesized by tandem catalytic glycosylation-spiroketalization of 3,4,5-tri-O-benzyl-beta-D-fructo- pyranose. Of the several protic acid catalysts which exist, 0.3 molar equivalent trifluoromethane sulfonic acid in toluene was found to be most effective to afford the dianhydride in good yield.
