Synthetic Route of 22990-19-8, Chemistry is the science of change. But why do chemical reactions take place? Why do chemicals react with each other? The answer is in thermodynamics and kinetics.In a document type is Article, and a compound is mentioned, 22990-19-8, 1-Phenyl-1,2,3,4-tetrahydroisoquinoline, introducing its new discovery.
Chiral Carboxylic Acid Enabled Achiral Rhodium(III)-Catalyzed Enantioselective C?H Functionalization
Reported is an achiral CpxRhIII/chiral carboxylic acid catalyzed asymmetric C?H alkylation of diarylmethanamines with a diazomalonate, followed by cyclization and decarboxylation to afford 1,4-dihydroisoquinolin-3(2H)-one. Secondary alkylamines as well as nonprotected primary alkylamines underwent the transformation with high enantioselectivities (up to 98.5:1.5 e.r.) by using a newly developed chiral carboxylic acid as the sole source of chirality to achieve enantioselective C?H cleavage by a concerted metalation-deprotonation mechanism.
Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law.Synthetic Route of 22990-19-8. In my other articles, you can also check out more blogs about 22990-19-8
