  Stereoselective Construction of C-13 Quaternary Carbon Unit of Isopimarane Diterpene and Its Synthetic Application to Isopimarol Diterpene

  摘要：

  Highly stereoselective construction of the C-13 quaternary carbon unit of isopimarane diterpene has been achieved by two consecutive alkylations of the tricyclic enone intermediate which was straightforwardly derived from the known decalone system. In addition, this procedure has been expanded to the general synthetic route to isopimarane diterpenes.
