通过双官能三乙二醇和烯丙基丙交酯之间的硫醇-烯化学合成了含三(乙二醇)的丙交酯类似物。随后的辛酸锡催化的开环聚合产生了明确的聚(丙交酯)-接枝-聚(乙二醇)共聚物,其分子量为6000 g/mol,多分散指数为1.6。沿着共聚物的三(乙二醇)链含有能够进行“点击”型聚合后官能化的叠氮化物末端。通过成功施陶丁格连接来安装 Gly-Arg-Gly-Asp-Ser (GRGDS) 肽,证明了该策略的实用性。
A tri(ethylene glycol)-containing lactide analogue was synthesized via thiol-ene chemistry between a bi-functional triethylene glycol and allyl lactide. Subsequent tin-octoate-catalyzed ring-opening polymerization yielded well-defined poly(lactide)-graft-poly(ethylene glycol) copolymers with molecular weights of 6000 g/mol and polydispersity indices of 1.6. The tri(ethylene glycol) chains along the copolymers contain azide termini that are capable of ‘click’-type postpolymerization functionalization. The utility of this strategy was demonstrated via successful Staudinger ligation to install the Gly-Arg-Gly-Asp-Ser (GRGDS) peptide.
