A new synthetic protocol has been developed for the arylation of secondary and N-alkylated amide Heck precursors by the implementation of the palladium-catalyzed intramolecular Heck reaction strategies.
A new synthetic protocol has been developed by the implementation of the palladium-mediated benzylic C-H activation followed by tethered intramolecular arylation strategy to give linearly fused and unusually oxidized pyridocoumarin derivatives. oxidation - C-H activation - biaryl coupling - intramolecular cyclization - palladium acetate
