An efficient diastereoselective synthesis of the spongian diterpenes (−)-spongian-16-oxo-17-al (1) and (−)-acetyldendrillol-1 (13) is described starting from (+)-podocarp-8(14)-13-one (6) via the ester-dialdehyde 11 as key intermediate. The absolute configuration at C-17 in synthetic compound 13 has conclusively been proved by NOE experiments.
