2,3:4,5-Di-o-isopropylidene-beta-D-fructopyranose

It serves as a protected carbohydrate scaffold, allowing the sulfamoylation of the C-1 hydroxyl group to introduce the necessary sulfamate functional group. D-fructopyranose (often called diacetone fructose) is a key,, essential starting material in the industrial synthesis of the anticonvulsant drug Topiramate.
