effective method for asymmetric cross-couplings of unactivated alkyl electrophiles has been developed, specifically, a nickel-based catalyst for stereoconvergent Suzuki reactions of homobenzylic bromides with alkylboranes. To the best of our knowledge, there are no previous examples of enantioselective Suzuki couplings of alkyl electrophiles (activated or unactivated). Both of the catalyst components
已开发出用于未活化的烷基亲电试剂的不对称交叉偶联的第一种有效方法,特别是用于高苄基溴与烷基硼烷的立体收敛 Suzuki 反应的镍基催化剂。据我们所知,之前没有烷基亲电试剂(活化或未活化)的对映选择性 Suzuki 偶联的例子。两种催化剂组分都是可商购的。
