摘要
合成了对羟基苯甲酸乙酯双侧臂取代的二氮杂18-冠-6衍生物L1,在盐酸中水解得到了对羟基苯甲酸双侧臂取代的二氮杂18-冠-6衍生物L2,用元素分析、红外光谱和核磁共振谱对新大环化合物进行了表征.
The new derivative of diazacrown ether with two ethyl parahydroxy benzoic acid ester side arms (L1) is designed and synthesized. L1 is hydrolyzed using hydrochloric acid and H2O (1: 1) and another derivative of diazacrown ether which contains two parahydroxybenzoic acid side arms (L2) is obtained. L1 and L2 have not been reported in other articles. Their structures are characterized by elemental analysis, ^1HNMR and IR spectra.
