Functionalizable monotelechelic polymers are useful materials for chemical biology and materials science. We report here the synthesis of a capping agent that can be used to terminate polymers prepared by ring-opening metathesis polymerization of norbornenes bearing an activated ester. The terminating agent is a cis-butene derivative bearing a Teoc (2-trimethylsilylethyl carbamate) protected primary
可官能化的单线聚合物是化学生物学和材料科学的有用材料。我们在此报告了一种封端剂的合成,该封端剂可用于终止由带有活化酯的降冰片烯的开环复分解聚合制备的聚合物。终止剂是带有 Teoc(2-三甲基甲硅烷基乙基氨基甲酸酯)保护的伯胺的顺式丁烯衍生物。聚合物的聚合后改性是通过用叠氮胺连接基酰胺化,然后用 Cu(I) 催化的叠氮化物-炔烃环加成与炔丙基糖来完成的。随后的 Teoc 脱保护和与异硫氰酸芘酯结合得到明确定义的末端标记的糖聚合物。
