The reaction of 2,3,4,6-tetra-O-benzyl-D-glucopyranosyl acetate with alcohols in the presence of 5 mol% ytterbium(III) tris[bis(perfluorobutylsulfonyl) amide] as an activator afforded the corresponding glucopyranosides in good yields. This ytterbium complex also activated the benzylated glucosyl donors having trichloroacetoimidate, fluoride, and methoxyacetate as the leaving groups.
