Popis:	Commercially available β - d -glucopyranose pentaacetate, β - d -galactopyranose pentaacetate and β - d -lactose heptaacetate were reacted with propargyl alcohol in the presence of BF 3 –Et 2 O catalyst to obtain in high yield and selectivity, the corresponding propargyl derivatives, respectively. These were hydrogenated by use of Lindlar catalyst to give the corresponding allyl β - d -glycopyranosides in quantitative yield.
