An efficient, stereocontrolled total synthesis of the complex indole-diterpene alkaloid (−)-21-isopentenylpaxilline (1) has been achieved. Key elements of the synthesis include the stereocontrolled construction of the advanced eastern hemisphere (−)-68, involving a highly efficient union of the eastern and western fragments (−)-68 and 5 exploiting our 2-substituted indole synthesis, application of
已经实现了复杂的吲哚-二萜生物碱(-)-21-异戊烯基帕西林(1)的高效,立体控制的全合成。合成的关键要素包括先进的东半球(-)- 68的立体控制结构,其中涉及利用我们的2取代的吲哚合成,东根和西碎片(-)- 68和5的高效结合,Negishi的应用π环烷基化策略是构建环C的新方法,可能是通用的协议,并且可以裂解β,γ-环氧酮,在吲哚二萜骨架的C(13)处引入叔羟基。
