Treatment of the acylated glycosyl halide (bromide or chloride) of the opposite anomeric configuration with silver fluoride in acetonitrile was the method initially developed40 for the synthesis of the less stable anomers, as exemplified by the synthesis of peracylated /S-D-glucopyranosyl fluoride40 from the corresponding a-bromide. It has... 

A mild stereoselective synthesis of arylthioglycosides has been accomplished via anomeric inversion during the nucleophilic reaction by aryl thiols on glycosyl halides [18, 19]. 

Most of the methods available for the synthesis of this class of compoimd have been referred to in the preceeding pages. These include the modified Koenigs-Knorr reaction (p. 406), the use of glycosyl halides with non-... 

The first synthesis of methyl 4-thiomaltoside (36b) (34%), 4-thiocellobioside (39d) (52%) and 4-thiodigalactobioside (86) (56%) was reported 18 years ago by using the Sn2 displacement of 1,2-cis- or 1,2-trans- glycosyl halides (9 a), (7 a) and (7c) with methyl 4-thio-a-D-glycopyranoside sodium salts generated from the acetylated methyl glycosides (84) and (85a) (Scheme 25) [14a].
