Enantioselective α‐arylation of racemicketones containing existing α′‐stereocenters is reported for the first time via base‐induced dynamic kinetic resolution. Bridged bicyclic rings are formed in good ee values, which are difficult to obtain otherwise. Furthermore, reactions in DMSO‐d6 resulted in extensive deuteration of both α‐ and α′‐positions in the products, thus supporting a pathway involving
首次通过碱诱导的动力学动力学解析报道了含有现有α'-立体中心的外消旋酮的对映选择性α-芳基化。桥接的双环以良好的ee 值形成,否则很难获得。此外,DMSO- d 6中的反应导致产物中α-和α'-位的大量氘化,从而支持了在催化条件下涉及酮快速,可逆的去质子化的途径。
