Synthesis Of Polysubstituted Pyrroles Through Electro-Oxidative Annulation Of 1,3-Dicarbonyl Compounds And Primary Amines

Reported herein is a synthetic method of poly-substituted pyrroles from easily available materials, 1,3-dicarbonyl compounds and primary amines, via electro-oxidative intermolecular annulation. Under similar conditions, enamines are also converted smoothly into desired products, indicating that in situ formed enamines are crucial intermediates for the first transformation. Neither transition-metal salts nor harsh conditions are required to facilitate the dehydrocyclization process.
