《Synthesis of Polysubstituted Pyrroles through Electro-Oxidative Annulation of 1,3-Dicarbonyl Compounds and Primary Amines》 was written by Xiong, Mingteng; Liang, Xiao; Zhou, Yifeng; Pan, Yuanjiang. SDS of cas: 30414-53-0 And the article was included in Journal of Organic Chemistry on April 2 ,2021. The article conveys some information:
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. In the experiment, the researchers used many compounds, for example, Methyl 3-oxovalerate(cas: 30414-53-0SDS of cas: 30414-53-0)
Methyl 3-oxovalerate(cas: 30414-53-0) belongs to ketone compounds. Ketone compounds have important physiological properties. They are found in several sugars and in compounds for medicinal use, including natural and synthetic steroid hormones. Molecules of the anti-inflammatory agent cortisone contain three ketone groups.SDS of cas: 30414-53-0
