Utilizing a late‐stage enamine bromofunctionalization strategy, the twelve‐step total synthesis of (−)‐huperzine Q was accomplished. Furthermore, the first totalsyntheses of (+)‐lycopladines B and C are described. An unprecedented X‐ray crystal structure of an unusual epoxyamine intermediate is also reported, and the synthetic application of this intermediate in natural product synthesis is demonstrated
