An efficient catalyst system for the asymmetric transfer hydrogenation of ketones: remarkably broad substrate scope.
J. Am. Chem. Soc. 128 , 1044, (2006) A BINOL-derived diphosphonite having a xanthene backbone is an excellent bidentate ligand in Ru-catalyzed 2-propanol-based transfer hydrogenation of aryl/alkyl and alkyl/alkyl ketones (ee = 76-99%). Even notoriously difficult ketones such as isopropyl methyl ... |
