Dysidiolide(1)是一种先前从加勒比海海绵Dydya etheria de Laubenfels分离出的新型酯类萜,可抑制磷酸酶cdc25A的作用。作者以旋光性环己烯酮3为分子内Diels-Alder反应为关键步骤,建立了一种新型的天然dysidiolide(1)的全合成。通过分子内Diels-Alder反应生成的二烯酯构建了萘烷,即1,的核心结构。通过从由环己烯酮3制备的亚砜酯6中消除苯基亚砜基,在C-7处进行非对映选择性甲基化,在C-6处进行烷基化,并在C-12和C-24处进行脱氧,从而得到1的完全取代的双环核。将双环核心的两个侧链进一步延伸,以提供天然的dysidiolide(1)。
Dysidiolide, a novel sesterterpenoid isolated from the Caribbean sponge Dysidia etheria de Laubenfels, has been shown an inhibitor of protein phosphatase cdc25A. The authors established a stereocontrolled totalsynthesis of (±)-dysidiolide using an intramolecular Diels–Alder reaction as the key step.
