transformations are based on the fact that DMF can serve as a reaction solvent and one carbon synthon for the construction of heterocyclic rings. Moreover, this protocol features base-free and Brønsted acid free environmentally benign conditions with broad synthetic scope. A good scalability is demonstrated.
Palladium-Catalyzed <i>Ortho</i>-Selective C–H Oxidative Carbonylation of <i>N</i>-Substituted Anilines with CO and Primary Amines for the Synthesis of <i>o</i>-Aminobenzamides
An efficient, one-pot strategy with high selectivity and high atom economy for the synthesis of o-aminobenzamides has been developed via palladium-catalyzed ortho-selective C–H oxidative carbonylation of N-substitutedanilines with CO and primary amines. A wide range of N-substitutedanilines and primary amines can be tolerated in this transformation to afford the corresponding o-aminobenzamides in
