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.
通过固相合成法生成了与2-氨基乙基连接体共轭的磺化葡糖胺(葡糖胺磺化形式)的单糖和二糖。将正交保护的中间体连接到三苯甲基化的聚苯乙烯树脂珠上,进行脱保护和磺化步骤的模块化序列,然后在不使用溶剂解条件降解N-或O-硫酸酯的情况下从固相载体上裂解下来,最后通过反相高效液相色谱法纯化,得到标题化合物。
