A simple copper-catalyzed synthesis of tertiary acyclic amides

Racine, Emilie,Monnier, Florian,Vors, Jean-Pierre,Taillefer, Marc

, p. 2818 - 2821 (2011/07/09)

The N-arylation of aromatic and aliphatic secondary acyclic amides, known to be poor nucleophiles, has been accomplished using a simple and cheap copper catalytic system. The corresponding tertiary acyclic amides, which can be found in numerous biologically active compounds, have been obtained in good to excellent yields.
