Convergent total synthesis of (+)-muricatetrocin B, a tetrahydrofuran-containing acetogenin with potent and selective cytotoxicity against the HT-29 human colon adenocarcinoma cell line, was achieved in 13 steps. Our synthesis is highlighted by a late-stage sequential olefin cross-metathesis/Hartung-Mukaiyama cyclization for convergent assembly of the 2,5--substituted tetrahydrofuran ring.
