Optically-active alpha-substituted phenylacetic acid is prepared from the corresponding racemic alpha-substituted phenylacetonitriles by racemization of recycle undesired optically-active acid, in the presence of water and base and the racemic nitrile, and recovering the desired optically-active alpha-substituted phenylacetic acid.
在水和碱以及外消旋腈的存在下,通过对回收的非光学活性酸进行消旋化,从相应的外消旋α-取代苯基乙腈中制备光学活性α-取代苯基乙酸,并回收所需的光学活性α-取代苯基乙酸。
