“…The notable advantage of a glycosyl fluoride as a glycosyl donor is its higher thermal and chemical stability relative to glycosyl chlorides, bromides, and iodides; it is possible to purify glycosyl fluorides by column chromatography on silica gel. Many methods for the preparation of glycosyl fluorides105 have been developed by using various fluorinating reagents such as HF106 2‐fluoro‐1‐methylpyridinium tosylate,107 diethylaminosulfur trifluoride (DAST),108–110 HF/pyridine,111–113 CF 3 ZnBr/TiF 4 ,114 DEAD/PPh 3 /Et 3 O⋅BF 4 ,115 selectfluor,116 deoxofluor,117 N , N ‐diisopropyl(1‐fluoro‐2‐methyl‐1‐propenyl)amine,118 HF/MeCN/Ac 2 O,119 AgF,120 ZnF 2 ,121 Et 3 N/HF,122 CF 3 ZnBr,114 DAST/ N ‐bromosuccinimide (NBS)/NIS,123, 124 4‐methyl(difluoroiodo)benzene,125 TBAF,126 and PhI(OAc) 2 /SiF 4. 127 Of these, DAST, HF/pyridine, and DAST/NBS are most frequently used.…”
