"Chemical Equation Presented" A one-step Pd-catalyzed reaction performed on an o-bromobenzamide permitted the selective formation of either phenanthridinones 2 via an ipso substitution or new phenanthridinone-1- carboxamides 3 through a direct N-arylation. A direct correlation between the solvent polarity and the carbonate base on the selectivity has been observed. The proposed catalytic cycle involves the initial formation of a common intermediate and depends on the base assistance.

(Chemical Equation Presented) A palladium-mediated domino reaction was developed to conveniently synthesize phenanthridinone derivatives. Phosphine ligand 1 strongly promotes the domino process, which includes aryl-aryl coupling and C-N bond formations concomitant with a deamidation reaction. The versatility and applicability to a broad range of substrates make this reaction useful for the development of bioactive derivatives.
