Less stable, but natural: The asymmetric total synthesis of leucosceptroid B (see scheme) has been accomplished in 19 steps. Thermodynamically, this natural product proved to be less stable than its C11 epimer, a synthetic intermediate. This synthesis features a high degree of flexibility, facilitating its application to the preparation of a broad range of other natural derivatives.
稳定性较差,但很自然:leucosceptroid B的不对称全合成(参见方案)已通过19个步骤完成。在热力学上,该天然产物证明不如其C11差向异构体(一种合成中间体)稳定。这种合成具有高度的灵活性,有助于其在制备其他多种天然衍生物中的应用。
