Recommanded Product: 119-61-9. Recently I am researching about 2-ACETYL-1-PYRROLINE; DEAROMATIZATION; ACETYLENES; VINYLATION; ALKALOIDS; CHEMISTRY; SUPERBASE; MYOSMINE; WATER, Saw an article supported by the Russian Science FoundationRussian Science Foundation (RSF) [19-13-00052]. Published in AMER CHEMICAL SOC in WASHINGTON ,Authors: Bidusenko, IA; Schmidt, EY; Ushakov, IA; Vashchenko, AV; Trofimov, BA. The CAS is 119-61-9. Through research, I have a further understanding and discovery of Benzophenone
N-Benzyl ketimines undergo [3 + 2] cycloaddition with arylacetylenes in the KOBut/DMSO solution to 2,3,5-triarylpyrrolines, which are oxidized (chloranil, DDQ) in situ to 2,3,5-triaryl-2H-pyrroles in 53-71% yields. The intermediate 1-pyrrolines can be isolated in 31-91% yields and separately oxidized to the corresponding 2H-pyrroles.
Recommanded Product: 119-61-9. Welcome to talk about 119-61-9, If you have any questions, you can contact Bidusenko, IA; Schmidt, EY; Ushakov, IA; Vashchenko, AV; Trofimov, BA or send Email.
