Starting from the reaction of thioquinanthrene 1 with sodium methoxide followed by the reaction with α,ω-dihalogenoalkanes, title bis-methoxy oligomers 4a-c with four 3,4-quinolinediyl units were prepared (40–91%). Acid catalysed hydrolysis of methoxy groups in 4a-c gave tetramers 5a-c (46–94%) with two 4(1H)-quinolinone functions. The reactions of bis-quinolinones 5a-c with phosphoryl chloride in
从硫代蒽1与甲醇钠反应开始,然后与α,ω-二卤代烷烃反应,制备了具有四个3,4-喹啉二烯基单元的标题双甲氧基低聚物4a-c(40-91%)。酸催化4a-c中甲氧基的水解产生具有两个4(1 H)-喹啉酮功能的四聚体5a-c(46-94%)。双喹啉酮5a-c与磷酰氯在DMF中的反应进行了脱氧氯化,得到了带有4-氯喹啉基的潮汐二氯四聚体6a-c(51-66%)。双甲氧基四聚体4a的处理-c与沸腾的磷酰氯反应生成标题α,ω-双(4-氯-3-喹啉基硫基)烷烃7a-c(52-56%)和硫代蒽(65-70%)。
