One-step synthesis of Lycopodium alkaloid (-)-huperzine W via Suzuki-Miyaura coupling

The first total synthesis of ( )-huperzine W (1) has been achieved. Key element of the synthesis is a highly convergent assemblage for the two rings system of target molecule utilizing an efficient Suzuki-Miyaura coupling reaction between chiral iodide 2 and 2-allylpyrrolidinone 4. Evaluation of the AchE inhibition of synthetic huperzine W was also carried out.
