A simple chemoenzymatic strategy for the incorporation of bioactive and suitably functionalized molecules into a polyester chain has been developed. The protocol involves first the reaction of a primary amine with ε-caprolactone to give an amide carrying a terminal primary hydroxy group, followed by the enzymatic growth of the polymeric chain triggered by Novozym 435. This method is versatile and easy
已经开发出一种用于将生物活性和适当官能化的分子掺入聚酯链的简单化学酶策略。该方案首先涉及伯胺与ε-己内酯的反应,以生成带有末端伯羟基的酰胺,然后由Novozym 435引发聚合物链的酶促生长。该方法用途广泛,易于操作,适用于如模型化合物苄胺和色胺,生物活性化合物N-去乙酰基硫代秋水仙碱以及官能化的炔丙基胺和酪胺所示,用于将不同的胺掺入聚酯中。
