The enantioselective total synthesis of the dual-specificity phosphatase inhibitor (−)-bitungolide F has been achieved using two convergent routes. Both strategies feature an asymmetric boron-mediated pentenylation, a stereoselective aldol, and a hydroxyl-directed 1,3-anti-reduction in order to control the stereogenic centers at C4, C5, C9, and C11. Whereas the first total synthesis was achieved in
