开链冠醚类似物(Ⅱ)——4-氧安替比林为端基的含氮开链冠醚等效物的合成与研究

Open-Chain Crown Ether Analogues ( Ⅱ )——Syntheses and Studies of Open Chain Equivalents of Azacrown Ether with End Groups of 4-Oxyantipyrine

本文合成了11种以4-氧安替比林为端基的含氮开链冠醚类似物,通过元素分析和波谱鉴定了它们的结构.报道了4-羟基安替比林O-烷基化的新方法.相转移催化性能研究表明,它们可以作为液-液相或固-液相转移的良好催化剂。

Eleven openchain azacrown ether analogues with the end groups of 4-oxyantipyrine (3a_k) were synthesized and identified by elemental analysis and spectral data. Two methods for O-alkylation of 4-hydroxyantipyrine are reported. The phase-transfer catalytic behaviour of the new compunds is studied. It is found that these compounds used either as liquid-liquid or as solid-liquid phase-transfer catalysts have good catalytic activity.
