N2 - Acetalation of sucrose with 2,2-dimethoxypropane in 1,4-dioxane in the presence of p-toluenesulfonic acid, followed by acetylation, afforded methyl 4,6-di-O-acetyl-1,3-O-isopropylidene-α-d-fructofuranoside and 4-O-acetyl-2,3:5,6-di-O-isopropylidene-d-glucose dimethyl acetal as major products, while tosylation of the intermediate acetals provided methyl 6-O-tosyl-1,3-O-isopropylidene-α-d-fructofuranose.
