摘要
用不对称二苯并14-冠-4-双羟基冠醚的顺式异构体(Ⅰ、Ⅲ)和反式异构体(Ⅱ)分别与丙二酰氯、丁二酰氧和己二酰氯反应,合成了14种桥链冠醚,用IR、~1H NMR、MS和元素分析确证了它们的结构。结果表明,顺式异构体与丁二酰氧和己二酰氧反应可生成1:1和2:2缩合物,而与丙二酰氯反应则只生成2:2缩合物;反式异构体与3种脂肪二酰氯反应都生成2:2缩合物。
Fourteen new bridged crown ethers have been synthesized by the reaction of asymmetrical cis-trans isomers of dibenzodihydroxy-14-crown-4 with malonyl dichloride, butanedioyl dichloride and hexanedioyl dichloride respectively. Their structures wer.e confirmed by IR, 1H NMR, MS and elemental analysis. The experimental results demonstrate that the cis isomers react with butanedioyl dichloride and hexanedioyl dichloride to form 1 ' 1 and 2 : 2 condensation compounds, while malonyl dichloride only to form 2 : 2 condensation compounds. The trans iso-mer reacts with the above three aliphatic acid dichlorides all to form 2 : 2 condensation compounds.
