Rh III ‐Catalyzed Direct C8‐Arylation of Quinoline N ‐Oxides using Diazonaphthalen‐2(1 H )‐ones: A Practical Approach towards 8‐aza BINOL

An efficient Rh III ‐catalyzed redox‐neutral method for the direct C8‐arylation of quinoline N ‐oxides using diazonaphthalen‐2(1 H )‐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. A plausible reaction pathway was proposed after carrying out preliminary control studies.
