The synthesis of enantiomerically pure norsesterterpene triene ester 1, extracted from an Australian marine sponge Latrunculia brevis, has been achieved by preparation of E,E-diene 3a via a Julia one-pot olefination and addition to 2,5,5,8a-tetramethyl-octahydro-naphthalen-1-one 5. The synthesis of Z,E-diene 3b, the putative biogenetic precursor of mycaperoxide B 2 has also been achieved following the same methodology.
