An efficient RhIII‐catalyzed redox‐neutral method for the direct C8‐arylation of quinoline N‐oxides using diazonaphthalen‐2(1H)‐one as coupling partner has been demonstrated. The developed method is simple, scalable and straightforward with a wide range of substrate scope. The applicative potential was extended with a late‐stage functionalization and straightforward synthesis of 8‐azaBINOL derivative
已经证明了一种有效的Rh III催化的氧化还原中性方法,该方法使用重氮萘2(1 H)-one作为偶合配偶体直接对喹啉N-氧化物进行C8芳基化。所开发的方法简单,可扩展且简单,具有广泛的基板范围。通过后期功能化和直接合成8-azaBINOL衍生物可以扩大应用潜力。在进行初步的对照研究后,提出了一个合理的反应途径。
