NBS/DAST

For a relevant example, see the synthesis of 95 depicted in Scheme 17.91 This procedure is based on the fact that such thioglycosides, as 89, could be readily converted into glycosyl fluorides (90) by treatment with NBS/DAST. The glycosyl... [Pg.183]

Glycosyl fluorides have been produced using numerous reagents [51], e.g. dimethyl(methylthio)sulfonium tetrafluoroborate (DMTSB) [52], NBS-DAST [53], HF/pyridine [53] and Selectfluor [54],... [Pg.102]
