Methyl 3-O-benzyl-4, 6-O-benzylidene-2-O-(trifluoromethanesulfonyl)-β-D-mannopyranoside (7) was examined as a substrate for the preparation of 2-deoxy-2-fluoro-D-glucose (1) by fluoride ion treatment. The triflate (7) reacted rapidly with tetraalkylammonium fluorides in acetonitrile or tetrahydrofuran to give methyl 3-O-benzyl-4, 6-O-benzylidene-2-deoxy-2-fluoro-β-D-glucopyranoside (10) in 52-57% yield. Removal of the protecting groups from 10 by the use of 50% methanesulfonic acid afforded the required 1 in good yield. This synthetic sequence may provide an effective alternative to known methods for preparing 18F-labeled 1.

9-isopropylidene ketal 7 (69%). Conditions were found which allow selective silylation at C-4 with tert -butylchlorodimethylsilane, giving the 4- O - tert -butylsilyl derivative in 91% yield Heating it with bis(tributyltin) oxide afforded the 1,7-lactone with inversion of the ring conformation. Lithium aluminiumhydride reduction of 7 afforded the corresponding methyl non-2-ulopyranoside, which was converted
