Only the mixture works! Acrylic acid derivatives with CF3 substituents in α or β position were efficiently hydrogenated in the presence of a RhI complex with a chiral secondary phosphine oxide (SPO; see scheme) and an achiral Ph3P as ligands. The corresponding propanoic acid derivatives were obtained with generally high conversion (>99 %) and high enantioselectivity (92–>99 %).

Construction of CF<sub>3</sub>-Containing Quaternary Chiral Centers <i>via</i> Michael Addition Reactions
Michael addition reactions of a variety of Grignardreagents to 4,4,4-trifluorinated α,β-unsaturated carboxylic acid derivatives with the 4-substituted oxazolidin-2-ones as the chiral auxiliary were found to occur smoothly in the presence of CuBr·SMe2 and TMSCl to construct the desired products with the quaternary stereocenters possessing a CF3 group in good to excellent yields.
发现在CuBr·存在下,以4-取代的恶唑烷-2-酮为手性助剂的各种格氏试剂对4,4,4-三氟代α,β-不饱和羧酸衍生物的迈克尔加成反应均能顺利进行。 SMe 2和TMSC1以具有良好至优异产率的具有CF 3基团的四级立体中心构建所需产物。
