Deoxyfluorosugars were synthesized rapidly by the reaction of trifluoromethanesulfonyl derivatives of partially protected sugars with tris(dimethylamino)sulfonium difluorotrimethylsilicate (TASF) under mild conditions. The displacements occurred with inversion of configuration; fluorine has been introduced stereospecifically at each of the secondary alcoholic sites of aldohexopyranosides and in one

The fluoride ion displacement of carbohydrate trifluoromethanesulphonates using tris(dimethylamino)sulphoniumdifluorotrimethylsilicate (TASF) provides a convenient route to deoxyfluorosugars; the rapidity of the reaction makes it of interest for the potential synthesis of fluorinated-carbohydrate radiopharmaceuticals for use in medical imaging.
