The title compound has been synthesized as its racemate in 33 steps. An intramolecular Diels−Alder reaction (see Scheme 5, 24 → 25) was used to provide control over the eventual cis C4−C7 relationship. The installation of another cis related ethynyl group at C2 arose from transformation 40 → 42 (see Scheme 8) whose directionality is governed by a benzophenone ketal functioning as a temporary steric
