The present invention provides processes for the production of chiral compounds in a stereoisomeric excess. The present processes involve reacting a hydrometallated alkene compound with a compound comprising a conjugated-bond system under conditions such that the compounds undergo an asymmetric 1,4- or 1,6-conjugate addition reaction, generating a chiral compound in a stereoisomeric excess. The reaction is performed in the presence of a metal catalyst, which catalyst preferably comprises a non-racemic chiral ligand.
本发明提供了用于在立体异构体过量中生产手性化合物的工艺。目前的工艺涉及将氢金属化的烯烃化合物与包含共轭键系统的化合物在条件下反应,使得这些化合物经历不对称的1,4-或1,6-共轭加成反应,生成手性化合物的立体异构体过量。反应在金属催化剂存在下进行,该催化剂最好包括非外消旋手性配体。
