The present invention relates to a process of manufacturing compound having stereogenic centres from a mixture of E/Z isomers of unsaturated compounds having prochiral double bonds. The hydrogenation product has a specific desired configuration at the stereogenic centres. The process involves two asymmetric hydrogenation steps. The process is very advantageous in that it forms the desired chiral product from a mixture of stereoisomers of the starting product in an efficient way.
本发明涉及一种从具有可拆手双键的E/Z异构体混合物中制造具有立体中心的化合物的过程。氢化产物在立体中心处具有特定的期望构型。该过程涉及两个不对称氢化步骤。该过程非常有利,因为它以高效的方式从起始产物的立体异构体混合物中形成所需的手性产物。
