Stilbenocrown ethers 3a,c and 4a,b were synthesized in a cyclization reaction of benzoin with oligoethylene glycol ditosylates(2a-c) under a phase-transfer condition. Extractions of aqueous alkali picrates(Na+–Cs+) were examined with the distilbenocrown ethers 4a,b, the partially-hydrogenated tetraphenylcrown ethers 6a,b and the fully-hydrogenated tetracyclohexylcrown ethers 7a,b.
在相转移条件下,在安息香与低聚乙二醇二甲苯磺酸酯 (2a-c) 的环化反应中合成了芪王醚 3a、c 和 4a、b。用二苯乙烯冠醚 4a、b、部分氢化的四苯基冠醚 6a、b 和完全氢化的四环己基冠醚 7a、b 检测碱性苦味酸盐 (Na+–Cs+) 的萃取。
