A one-pot, two-step method for the preparation of degradable PEG is here presented. The full process addresses the requirements imposed by green chemistry and involves the use of a single and nontoxic non-eutectic mixture of organocatalysts. The strategy relies on the polycondensation of PEG800 after its functionalization by bio-derived 5-membered γ-butyrolactone.
本文提出了一种一锅两步法制备可降解聚乙二醇(PEG)的方法。整个过程满足了绿色化学的要求,且使用了单一无毒的非共晶有机催化剂混合物。该策略基于生物衍生的五元γ-丁内酯对PEG800进行功能化后再进行缩聚反应。
