  The First Total Synthesis of (±)-Huperzine B

  摘要：

  Huperzine B, a new Lycopodium alkaloid, exhibits a memory facilitating effect in mice and may be useful as an acetylcholinesterase inhibitor for the treatment of Alzheimer's disease. An efficient synthetic approach to huperzine B has been established successfully. The tetracyclic intermediate 10 is constructed by means of a tandem Michael addition and intramolecular Mannich cyclization using 8 and 9 as two components. Racemic huperzine B is obtained via a reaction sequence of 12 steps in 6.6% overall yield.
