An acid-catalyzed reaction of 2,3:4,6-di-O-isopropylidene-α-l-sorbofuranose with ketones resulted in replacement of the isopropylidene groups with alkylidene groups derived from the ketonic solvent. Kinetically controlled exchange occurs at the 4,6-position. Under equilibrium conditions exchange occurs at the 2,3- as well as the 4,6-position. Participation by the hydroxyl group at C-1 in the rate determining step of exchange at the 2,3-position could not be demonstrated.
