Xiong, Mingteng published the artcileSynthesis of Polysubstituted Pyrroles through Electro-Oxidative Annulation of 1,3-Dicarbonyl Compounds and Primary Amines, Synthetic Route of 30414-53-0, the publication is Journal of Organic Chemistry (2021), 86(7), 4986-4993, database is CAplus and MEDLINE.
Synthetic method of polysubstituted pyrroles I [R1 = H, 2-Me, 2-MeO, etc.; R2 = Me, Et; R3 = Me, Et, i-Pr] from easily available materials, 1,3-dicarbonyl compounds and primary amines, via electro-oxidative intermol. annulation was reported. Under similar conditions, enamines were also converted smoothly into desired products I, indicating that in situ formed enamines were crucial intermediates for the first transformation. Neither transition-metal salts nor harsh conditions were required to facilitate the dehydrocyclization process.
