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
