Total synthesis of the proposed structure of didemnaketal B has been accomplished. The C7–C21 spiroacetal domain was synthesized by exploiting our Suzuki–Miyaura coupling/spiroacetalization strategy. The C1–C7 acyclic domain was constructed via an Evans syn-aldol reaction and a vinylogous Mukaiyama aldol reaction. Finally, the C22–C28 side chain was introduced by means of a Nozaki–Hiyama–Kishi reaction
