New discoveries in chemical research and development in 2021. As an important bridge between the micro and macro material world, chemistry is one of the main methods and means for humans to understand and transform the material world. 144690-92-6, Name is Triphenyl methyl olmesartan, molecular formula is C48H44N6O6. In an article, author is Tanaka, Ken,once mentioned of 144690-92-6, Safety of Triphenyl methyl olmesartan.
Rhodium-catalyzed Highly Enantioselective [4+2] Annulation of 2-Alkynylbenzaldehydes with Acyl Phosphonates
A cationic rhodium(I)/(R)-Segphos (R) [(4A’-bi-1,3-benzo-dioxole)-5,5′-diylbis(diphenylphosphine)] complex catalyzes the highly enantioselective [4+2] annulation of 2-alkynyl-benzaldehydes with acyl phosphonates, leading to benzopyranones with a phosphonate-substituted quaternary carbon center in moderate to high yields with excellent ee’s.
The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 144690-92-6 is helpful to your research. Safety of Triphenyl methyl olmesartan.
