摘要：合成了侧链带有手性氨基酸基团的烯二炔化合物,利用烯二炔化合物在加热或者光照条件下能够发生Bergman环化反应生成双自由基这一特点,制备了侧链含有手性中心的手性聚合物。红外光谱和核磁共振结果证实该烯二炔化合物发生了Bergman环化反应,凝胶渗透色谱结果证实获得了高分子量聚合物,圆二色光谱结果证实通过Bergman环化反应制备的聚合物具有主链手性。
Enediyne compounds with chiral amino acid ester groups were synthesized and used as monomers to synthesize chiral polymers. When heated or shined with ultraviolet light, the enediyne compounds undergo Bergman cyclization reaction with diradical intermediates, forming chiral polymers through the coupling reaction of these diradicals. The Bergman cyclization was confirmed by infrared and nuclear magnetic resonance spectroscopy. Gel permeation chromatography results showed that high molecular mass polymers were formed. The main chain chirality of these polymers was further confirmed by circular dichroism analysis.
