Ynamides are tested as new partners in radical and organometallic transformations. A radical cascade involving a 5-exo-dig cyclization followed by a 6-endo-trig radical trapping transforms ynamides into hetero-polycyclic compounds such as isoindoles, isoindolinones and pyrido-isoindolones. Various ene–tosylynamides react with platinum(II) chloride and lead to bicyclic nitrogenated heterocycles. This

The synthesis of quinazolinone derivatives was achieved from 2-iodobenzamide derivatives and various benzylamines, allylamine, and cinnamylamine derivatives through a one-pot copper-catalyzed reaction. In this reaction, the amine component (benzylamine/allylamine/cinnamylamine) is N-arylated with 2-iodobenzamide derivatives through Ullman coupling, followed by an intramolecular C–H amidation in the

Furans may be ring opened via pallado-catalyzed reactionsleading to alpha,beta-unsaturated aldehydes and ketones tethered to indole and isoquinoline moieties. Besides their synthetic interest, these fragmentations bring interesting elements into the discussion around the reaction mechanisms involved in palladium C-H activations of electron-rich heterocycles.
