Abstract
2,3,1′,3′4′,6′-Hexa- O-benzylsucrose was obtained by mild acid-catalysed hydrolysis of the 4,6- O-isopropylidene derivative and then converted into its 4,6-di- O-mesyl derivative. Selective displacement of this disulphonate with fluoride anion (from tetrabutylammonium fluoride) then afforded the 6-fluoro-4-mesylate. Removal of the protecting groups yielded 6-deoxy-6-fluorosucrose, which was characterised as its crystalline hepta-acetate. A derivative of 6-deoxy-6-fluoro- galacto-sucrose was formed when the above 6-fluoro-4-mesylate was subjected to nucleophilic displacement with benzoate anion.
