examined with a variety of aldehydes (e.g., 39, 59, and 62). Construction of 38 was thus achieved from vinyl triflate 36 and the ring B aldehyde 39. However, the projected intramolecular Michael addition (41 — ■ 1 42) and reductive hydroxy ketone cyclization (47 48) failed to yield ring C. Fetizon cyclization afforded the pentacyclic lactone (CDEFG) (51 — * 52), which resisted further useful functionalization
