Application of 1486-28-8, Catalysts allow a reaction to proceed via a pathway that has a lower activation energy than the uncatalyzed reaction. 1486-28-8, Name is Methyldiphenylphosphine, SMILES is CP(C1=CC=CC=C1)C2=CC=CC=C2, belongs to chiral-phosphine-ligands compound. In a article, author is Mirco, Abbinante Vincenzo, introduce new discover of the category.
TetraPh-Tol-BITIOPO: a new atropisomeric 3,3 ‘-bithiophene based phosphine oxide as an organocatalyst in Lewis base-catalyzed Lewis acid mediated reactions
A new chiral phosphine oxide based on a 3,3 ‘-bithiophene scaffold (TetraPh-Tol-BITIOPO) was synthesized, fully characterized and separated into antipodes through chiral HPLC. This new compound was successfully employed as an organocatalyst in Lewis base-catalyzed Lewis acid mediated reactions involving trichlorosilyl compounds. The new atropisomeric catalyst was able to promote the allylation of aldehydes with allyltrichlorosilane in up to 98% yield and up to 96% enantiomeric excess (ee), and the direct aldol reaction to afford beta-hydroxy ketones and beta-hydroxy thioesters, with good chemical yields and modest stereochemical efficiency. Computational studies helped to elucidate and to rationalize the stereochemical outcome of the reactions catalyzed by TetraPh-Tol-BITIOPO that was found to favour the formation of the isomer with an opposite absolute configuration in comparison with the products obtained with the previously reported 3,3 ‘-bithiophene-based catalyst.
Application of 1486-28-8, The reactant in an enzyme-catalyzed reaction is called a substrate. Enzyme inhibitors cause a decrease in the reaction rate of an enzyme-catalyzed reaction.I hope my blog about 1486-28-8 is helpful to your research.
