  Synthesis of the reported structure of herbolide I and its C-11 epimer from artemisin

  摘要：

  Artemisin (1) was converted into 12 (the reported structure for herbolide I) and its C-11 epimer 19 via a synthetic pathway involving a functionality transfer from C-8 to C-9 and an A-ring refunctionalization. The H-1 and C-13 NMR data of synthetic products 12 and 19 reveal that the assigned structure of the natural herbolide I is erroneous.

  Functionality transfer from C8 to C9 in sesquiterpenes. Synthesis of the named Herbolide E from artemisin.

  摘要：

  The key intermediate 6 was obtained in five steps from artemisin (1). The spectroscopic characteristics of the synthetic product 7a reveal that the proposed structure for the natural herbolide E must be revised.
