Abstract
Commercially available 2,3,4,6-tetra-O-benzyl-D-glucopyranose, activated by trifluoroacetic anhydride reacts, in the presence of Lewis acids, with various silyl enol ethers or with allylsilane to yield C-D-glucopyranosyl derivatives of the α-configuration, and with activated aromatic nucleophiles to yield the corresponding β-anomers.Keywords
