COA of Formula: C8H6O2. The Name is Isobenzofuran-1(3H)-one. Through research, I have a further understanding and discovery of 87-41-2.
For the metal-catalyzed asymmetric hydrogenation of alpha-substituted ketones, cis reductive products are generally obtained due to steric hindrance of substituents. Herein, an unprecedented trans reductive products were observed in palladium-catalyzed hydrogenative desymmetrization of cyclic and acyclic 1,3-diketones, providing the chiral trans beta-hydroxy ketones with two adjacent stereocenters including one alpha-tertiary or quaternary stereocenter with high enantioselectivity and diastereoselectivity. Mechanistic studies and DFT calculations suggested that the rarely observed diastereoselectivity reversal is ascribed to the charge-charge interaction between the palladium and aromatic ring of the substrate, which could not only result in the reversal of the diastereoselectivity, but also improve the reactivity.
