由于开链冠醚类似物具有某些与冠醚类似的性能,且合成操作简便,成本较低,配位作用迅速,引起了人们的研究兴趣。Vogtle等在研究末端带取代基的短链开链冠醚类似物基础上,提出了“末端基概念”,指出末端基的结构对这类化合物的性能有很大影响。现已见报道的末端基尚不多。作者以4-氧安替比林及4-氧硫代安替比林作为新的末端基,合成了开链冠醚类似物1-8 Because the open-chain crown ether analogs have certain properties similar to those of crown ethers, and the synthesis is simple, the cost is low, and the coordination effect is rapid, arousing people’s interest in research. Based on the study of short-chain open-chain crown ether analogues with substituents at the end, Vogtle et al. Proposed the “end-group concept” and pointed out that the structure of the terminal groups has a great influence on the performance of these compounds. There are not many reported end groups yet. The authors used 4-oxo-antipyrine and 4-oxothiopyrylin as new terminal groups and synthesized open-chain crown ether analogs 1-8
