enantiomeric excess (71%–83% ee). Ru-BINAP-catalyzed hydrogenation converted 2-trifluoromethyl-acrylic acid to the corresponding saturated acid, the ester-ification and reduction of which gave optically active 2-(trifluoromethyl)propan-1-ol in 80% ee.
Ru-BINAP和Rh-BINAP催化的(E)-2-(三氟甲基)alk-2-en-1-醇的氢化反应对映体过量(71%–83%ee)。Ru-BINAP催化的氢化将2-三氟甲基-丙烯酸转化为相应的饱和酸,对其进行酯化和还原,得到80%ee的旋光的2-(三氟甲基)丙-1-醇。
