A concise synthesis of the isolaurepinnacin skeleton 6 was achieved via the intermolecular allylation of the α-acetoxy ether 3 followed by ring-closing metathesis. This methodology was successfully applied to the convergent synthesis of the oxocene 15, an advanced synthetic intermediate for the total synthesis of laurencin.
通过α-乙酰氧基醚3的分子间烯丙基化,然后进行闭环易位,实现了异脲雷那星骨架6的简明合成。该方法已成功地应用于茂新世15的收敛合成,该新世代是月桂霉素全合成的高级合成中间体。
