A totalsynthesis of the novel neuritogenic agent (+)-epolactaene ((+)-1) has been achieved via a convergent route that utilized epoxyamide 8, C7–C11 fragment 7, and C1–C6 Wittig reagent derived from phosphonium salt 19 followed by cyclization to form the lactam. The absolute configuration of natural epolactaene is definitively established as (13R, 14R). Synthesis of (−)-1, the enantiomer of this natural
