The reagent combination scandium(III) trifluoromethanesulfonate and acetic anhydride efficiently cleaves oligosaccharides bound to the polyethylene glycol (PEG) polymer-support via the dioxyxylene (DOX) linker. Unexpectedly, the site of cleavage is between the DOX linker and the PEG polymer. This method of cleavage allows for the use of DOX as a linker for synthesis on polystyrene-polyethylene glycol, PS-PEG beads.
