Coupling with inversion: Chiral diarylmethanol derivatives undergo a stereospecific nickel‐catalyzed cross‐coupling reaction with aryl Grignard reagents (see scheme). The reaction proceeds with inversion of configuration and high enantiospecificity. The method has been applied to the asymmetric synthesis of a triarylmethane‐based anti‐cancer compound.
与反转偶联:手性二芳基甲醇衍生物与芳基格氏试剂进行立体定向的镍催化交叉偶联反应(参见方案)。该反应随着构型的转化和高对映体特异性而进行。该方法已应用于基于三芳基甲烷的抗癌化合物的不对称合成。
