【摘要】 采取两种不同的方法,即分别以氨基乙酸和二溴二苯并-18-冠-6(摩尔比为2∶1)或者以氯乙酸和二氨基二苯并-18-冠-6(摩尔比为2∶1)为原料,在回流温度下,合成氨基乙酸衍生二苯并-18-冠-6,其中用二氨基二苯并-18-冠-6和氯乙酸作用下,回流7 h产率较高,可达80%。目标化合物由红外、核磁共振及元素分析等手段进行表征。更多还原

【Abstract】 Glycine derivative of dibenzo-18-crown-6 was synthesized in two different ways.One used dibromo-dibenzo-18-crown-6 and amino acetic acid as raw materials,and the other used 4,4′-diamino-dibenzo-18-crown-6 and 1-chloro acetic acid as raw materials under refluxed conditions.The second method was better.Under optimum conditions,the product yield was nearly 80%.The product was characterized by IR,~1H NMR and elemental analysis.更多还原
