Popis: The intramolecular glycosidation of the 1-C-alkyl-D-hexopyranose derivatives to form the anhydroketopyranoses having 6,8-dioxabicyclo[3.2.1]octane structures was investigated. We synthesized several l-C-alkyl-2,3,4-tri-O-benzyl-D-hexopyranoses and found that only 5 mol% trifluoromethanesulfonic acid efficiently promoted the intramolecular glycosidation to afford the desired anhydroketopyranoses in good yields.
