A convenient synthetic method for 2-polyfluoroalkylated quinoline systems through the efficient generation of perfluoroalkylated imine from o-vinylanilines with perfluorinated hemiacetals or aldehyde hydrates was developed. In most cases, the major products are 2-polyfluoroalkyl-1,2-dihydroquinoline derivatives 3, which can be converted to either quinolines or 1,2,3,4-tetrahydroquinolines.
通过从邻乙烯基苯胺与全氟化半缩醛或醛水合物高效生成全氟烷基化的亚胺,开发了一种方便的2-多氟烷基化喹啉体系的合成方法。在大多数情况下,主要产品是2-聚氟烷基-1,2-二氢喹啉衍生物3,它们可以转化为喹啉或1,2,3,4-四氢喹啉。
