  Asymmetric Total Syntheses of Two Phlegmarine-Type Alkaloids, Lycoposerramines-V and -W, Newly Isolated from Lycopodium serratum

  摘要：

  Two new Phlegmarine-type alkaloids, lycoposerramines-V and -W, were isolated from Lycopodium, serratum, and their structures including the absolute configuration were established by asymmetric total synthesis involving such key steps as Johnson-Claisen rearrangement, asymmetric allylation, and ring-closing metathesis (RCM)- or Sml(2)-mediated stereoselective piperidine ring construction.
