Disclosed is a method of making β-polypeptides. The method includes polymerizing β-lactam-containing monomers in the presence of a base initiator and a co-initiator which is not a metal-containing molecule to yield the product β-polypeptides. Specifically disclosed are methods wherein the base initiator is potassium t-butoxide, lithium bis(trimethylsilyl)amide (LiN(TMS)2), potassium bis(trimethyl-silyl)amide, and sodium ethoxide, and the reaction is carried out in a solvent such as chloroform, dichloromethane, dimethylsulfoxide, or tetrahydrofuran.
本发明公开了一种制造β-多肽的方法。该方法包括在碱引发剂和非含金属分子的助引发剂存在下,使含β-内酰胺的单体聚合,生成β-多肽。具体公开的方法是碱引发剂为叔丁醇钾、双(三甲基硅基)酰胺锂(LiN(TMS)2)、双(三甲基硅基)酰胺钾和乙醇钠,反应在氯仿、二氯甲烷、二甲亚砜或四氢呋喃等溶剂中进行。
