The tetracyclic epoxide16 was prepared in stereocontrolled fashion from 4,4-dimethylcyclohexanone, the key steps being Saegusa ring expansion of its silyl enol ether to 5, ortho ester Claisen rearrangement of 7, and cyclization of 9 without rupture of the three-membered ring. Epoxide16 had previously been transformed into dactylol, thus completing the formal total synthesis.
