The synthesis of the marine sesquiterpene quinone (+)-hyatellaquinone (1) was achieved starting from the sesquiterpene aldehyde (+)-albicanal ((+)-3) (Schemes 3 and 4). Coupling of (+)-albicanal with 2,3,5,6-tetramethoxyphenyllithium led to the aryl-sesquiterpene system, which was modified to the target molecule. Furthermore, the first total synthesis of the marine compound spongiaquinone (2) was carried
从倍半萜醛(+)-白色醛((+)- 3)(方案3和4)开始,实现了海洋倍半萜烯醌(+)-杂萘醌(1)的合成。(+)-白色醛与2,3,5,6-四甲氧基苯基锂的偶联导致芳基-倍半萜烯系统,该系统被修饰为目标分子。此外,海洋化合物海绵醌(2)的第一个全合成是从((-)-白色(3)-3)开始的,其反应顺序包括立体选择性CC键加氢和一锅AcOH消除/去甲基化反应(方案7和10)。1和2的1,2-和1,4-苯醌形式的出现取决于溶剂系统的pH值。
