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.
已成功合成来自澳大利亚海绵Latrunculia brevis的对映体纯norsesterterpene三烯酯1,方法是通过朱利亚一锅反应法合成E,E-二烯3a,并将其加入2,5,5,8a-四甲基-八氢萘-1-酮5。同时,按照相同的方法也成功合成了Z,E-二烯3b,后者被认为是真菌过氧化物B 2的假定生物前体。
