Fluorination of methyl 2-O-benzyl-3,6-dideoxy-α-D-ribo- and α-D-arabino-hexopyranosides (1 and 4) with dithylaminosulfur trifluoride (DAST) yielded methyl 2-O-benzyl-3,5,6-trideoxy-5-fluoro-β-L-arabino-β-L-ribo-hexofuranosi des (3 and 6), respectively, al
Fluorination reactions at C-4 of methyl 2-O-benzyl-3,6-dideoxyhexopyranosides with diethylaminosulfur trifluoride (DAST) and with tris(dimethylamino)sulfonium difluorotrimethylsilicate (TASF)

Fluorination at C-4 of methyl 2-O-benzyl-3,6-dideoxy-α-D-ribo- and α-D-arabino-hexopyranosides (1 and 5) using diethylaminosulfur trifluoride (DAST) proceeded with exclusive retention of configuration. But treating the triflates of 1 and 5 with tris(dimethylamino)sulfonium difluorotrimethylsilicate (TASF) afforded mostly the configurationally inverted fluorides.
