氮支冠醚二硫代甲酸酯化合物的合成

Syntheses of the Esters of N-Pivot Crown Ether Dithiocarbamic Acid

报道合成氮支冠醚的一种新连接方法。２，３－苯并－１０－氮杂－１，４，７，１３－四氧杂环十五－２－烯与二疏化碳在氢氧化钠存在下反应生成胺基二硫代甲酸盐，然后与卤代烃连接，形成单、双、叁冠醚。

A novel method for the synthesis of N-pivot crown ethers is described. It is basedon the reaction of 2,3-benzo-l0-aza-l,4,7 ,13-tetraoxacyclopentadeca-2-ene with carbondisulfide in the presence of sodium hydroxide,which gave a sodium salt of substituted dithio-carbamic acid in gdod yield.The latler underwent a nucleophilic substitution with some alkylhalides,giving mono-,di-and tri-crown ethers,
