A highly regioselective de-aryloxylative amination of O- or N-chelating group-functionalized 2-aryloxy quinolines has been accomplished by means of a copper catalyst. The chelating functional groups of the substrate play a crucial role in directing the C-2-selective amination process, which proceeds through a novel aromatic nucleophilic substitution of the aryloxy group. The methodology provides expedient
通过铜催化剂已经完成了O-或N-螯合基团官能化的2-芳氧基喹啉的高度区域选择性的脱芳氧基胺化。底物的螯合官能团在指导C-2-选择性胺化过程中起着关键作用,该过程通过芳氧基的新型芳香亲核取代进行。该方法可方便地获得一类重要的功能化2-氨基喹啉(分离产率高达88%),并已成功地用于重要生物活性PRMT5抑制剂关键片段的合成。
