A method for asymmetric alkyl-alkyl Suzuki reactions of unactivated secondary alkyl electrophiles, specifically, cross-couplings of racemic acylated halohydrins with alkylborane reagents, has been developed. A range of protected bromohydrins, as well as a protected chlorohydrin and a homologated bromohydrin, are coupled in good ee by a catalyst derived from commercially available components.
一种用于非活化仲烷基亲电试剂的不对称烷基-烷基铃木反应的方法,特别是外消旋酰化卤代醇与烷基硼试剂的交叉偶联反应,已经被开发出来。一系列受保护的溴代醇,以及一个受保护的氯代醇和一个同系化的溴代醇,都可以通过商业可得的组分衍生的催化剂以高对映选择性进行偶联。
