The natural alkaloid (−)-huperzine A is an inhibitor of AChE and has been demonstrated to exert neuroprotection and to possess other CNS related properties. In this manuscript, we report the synthesis of the analogs of huperzine A, in their enantiomeric form, starting from a common precursor, that has the advantage of being easily prepared in both the enantiomeric forms, in high enantiomeric excess, and at moderate costs.
