Nucleophilic ringopening reactions of benzyl 2,3 anhydro-α-D-ribopyranoside with different nucleophiles resulted in exclusive formation of 3-substituted-3-deoxyxylose derivatives in good yields. The regiochemical outcome of the ringopening reaction is controlled by a polar repulsive interaction between the entering nucleophile and the pyranose oxygen lone pair of electrons.
