摘要: 将二氮杂18-冠-6的乙腈溶液分别与2-氯乙基烷基硫醚、2-氯乙基烯丙基硫醚、[2、(2-氯乙基)硫乙基]烷基硫醚在无水碳酸钾存在下反应制得5种新型侧链上含硫原子的双臂套索冠醚和5种新型单臂套索冠醚。它们的收率分别为37%~72%和13%~37%.此法比其它制备单臂套索冠醚的方法操作简便。

Abstract: Five new bibracchial lariat Ethers(double armed diaza crown ethers)containing sulfur donor atoms in the side arms were synthesized in 37%─72%yield by treating the acetonitrile solution of diaza-18-crown-6 with 2-chloroethyl alkyl sulfide, 2-chloro allyl sulfide, [2-(2-chloroethyl)thioethyl]alkyl sulfide in the presence of anhydrous sodium carbonate.The corresponding lariat ethers(single armed diaza crown ethers) were obtained simutaneously in 13%─37%yield. Therefore this is a facile method for the synthesis of single armed diaza crown ethers.
