摘      要：Rh(III)‐catalyzed C–H activation of N‐protected anilines and chemo‐divergent couplings with acroleins/enones have been realized for synthesis of three classes of *** oxidative coupling of N‐pyridylaniline afforded dihydroquinolones with the acrolein being a major hydrogen *** the directing group was replaced by pyrimidyl in the same system,redox‐neutral coupling occurred to afford hemiaminal *** annulation of N‐pyridylanilines with enones using AgBF4 oxidant afforded atropisomeric quinolinium salts.
