Mono- and disaccharides of sulfonated glucosamines (GlcN sulfoforms) conjugated to 2-aminoethyl linkers were generated by solid-phase synthesis. Orthogonally protected intermediates were tethered onto tritylated polystyrene resin beads, subjected to a modular sequence of deprotection and sulfonation steps, then cleaved from solid support without degradation of N- or O-sulfate esters using solvolytic conditions, and finally purified by reverse-phase HPLC to afford the title compounds.
