A catalytic asymmetric reduction process, which, by hydrogenating trisubstituted olefins, yields a corresponding organic compound having a high level of enantiomeric purity is disclosed. The reduction process utilizes a chiral metal catalyst that includes a metal or metal complex that is selected from groups 3, 4, 5, or 6, lanthanides and actinides. Moreover, the process uses hydrogen as the stoichiometric reducing agent and may be carried out at pressures ranging from about 1 to 200 atmospheres.
揭示了一种催化不对称还原过程,通过加氢三取代烯烃,产生具有高对映纯度的相应有机化合物。还原过程利用手性金属催化剂,其中包括从3、4、5或6组、镧系和锕系金属或金属配合物中选择的金属。此外,该过程使用氢作为量化还原剂,可在大约1至200个大气压范围内进行。
