A new type of azacrown ether crosslinked chitosan was synthesized by reaction of chitosan with dihydroxy mesocyclic diamine activated by epoxidation. 以壳聚糖为原料，与经环氧活化的双羟基中环二胺反应，制备了一种新型的氮杂冠醚交联壳聚糖。
In this paper we prepared a series of azacrown ethers with side chains of tropone rings and their derivatives by the reactivity of seven-membered aromatic tropone rings. 本文利用七元芳香卓酮环的反应活性，合成出了一系列以卓酮环及其衍生物为侧臂的氮杂冠醚。
