Regiodivergent Arylation of Pyridines via Zincke Intermediates
Abstract: An arylation protocol for pyridines is described, via the ring‐opened Zincke intermediate. Treatment of pyridines with triflic anhydride and a secondary amine produces an azahexatriene species, which undergoes regioselective Pd‐catalyzed arylation at the putative C4 position. Recyclization then provides the pyridine products. Alternatively, metal‐free arylation with a diaryliodonium salt is selective for the pyridine meta‐position, affording a regiodivergent approach to pyridine biaryls from a common intermediate.
