Hydrogenation of trisubstituted acrylic acids (()- and ()MeC(R)CPhCOOH: R = CD3, Et, Ph) in the presence of a chiral (aminoalkyl)ferrocenylphosphine-rhodium catalyst installed asymmetric configurations at two vicinal carbons at once giving optically active carboxylic acids of high enantiomeric purities (80% ee).
三取代丙烯酸(()-和()MeC(R)aCPhCOOH:R = CD 3,Et,Ph)在手性(氨基烷基)二茂铁基膦-铑催化剂存在下,在两个邻位碳上以不对称构型存在下进行氢化一次得到高对映体纯度(80%ee)的光学活性羧酸。
