wide array of enantioconvergent cross-couplings of arylzinc reagents with CF3-substituted racemic secondary alkyl halides, a process that necessitates that the chiral catalyst be able to effectively distinguish between a CF3 and an alkyl group in order to provide good ee. We further demonstrate that this method can be applied without modification to the catalytic asymmetric synthesis of other families
在本报告中,我们确定了一种容易获得的镍/双(恶唑啉)催化剂实现了芳基锌试剂与 CF3 取代的外消旋仲烷基卤化物的广泛对映收敛交叉偶联,这一过程需要手性催化剂能够有效地区分 CF3 和烷基以提供良好的 ee。我们进一步证明,该方法无需修改即可应用于其他氟化有机化合物家族的催化不对称合成。
