Total synthesis of (+)-tanikolide, a bioactive δ-lactone of marine origin, was successfully accomplished by utilizing a bromoalkene derivative conveniently synthesized from the corresponding 1-acyloxy-2,3-dibromoalkane by the regioselective and mild HBr-elimination reaction, along with the Pd-mediated C–C coupling reaction and the Sharpless asymmetric epoxidation as key steps.
通过区域选择性和温和的 HBr-消除反应,以及 Pd 介导的 C-C 偶联反应和 Sharpless 不对称环氧化反应等关键步骤,利用方便地从相应的 1-acyloxy-2,3-dibromoalkane 合成的
