The stereoselective synthesis of oletinated sugars at the anomeric center via Wittig reaction of a$giycosyl phosphonium tetrafluoroborates, easily prepared from a& methoxy glycosides, is described.
Stereoselective Synthesis of Olefinated Sugars. -The title compounds, e.g. (III), (IV), (VI) and (VII) are prepared via Wittig reaction. Highest yields are obtained using method A whereas method B leads to highest selectivities.
