A highly enantioselectivesynthesis of the (8S,12S)-enantiomer of preclavulone A and its methylester is described featuring the Julia protocol for installing the (Z)-double bond in the lower chain. This procedure is suitable for the preparation of labeled preclavulone analogues for biosynthetic studies on marine clavulones.

The totalsynthesis of preclavulone-A methylester and its diastereomer was achieved from same key intermediate in diastereoselective manner. These compounds are recognized as important intermediates in a proposed biosynthesis of marine prostanoids from the Okinawan soft coral, Clavularia viridis, and were recently isolated from the extract of C. viridis by our group.
