  摘要：

  Our first target on the way towards the synthesis of enantiomerically pure chatancin is the preparation of the title compound. The cycloadduct of 5,5-dimethoxy- 1,2,3,4-tetrachlorocyclopentadiene and thymoquinone is stereo- and regioselectively reduced to the tricyclic ketoalcohol 4, which by nucleophilic cyclisation and reductive removal of the keto group as well as the chlorine atoms yielded a tetracyclic dimethoxyketal. Acidic hydrolysis freed the keto group, which now was treated with a chiral lithium alkyl compound derived from methyl (R)-2-methyl-3-hydroxypropionate in few steps. The resulting stereomeric tertiary alkohols were fragmented and the decalinones thus obtained separated. X-ray analysis permitted the determination of the absolute configuration of these decalinone derivatives.

  As an antagonist of the platelet activating factor, chatancin (1), which is isolated from a soft coral, is of potential therapeutic use. The first total synthesis [Eq. (1)] of this structurally unusual diterpene in racemic form is described along with the formal total syntheses of natural (+)-chatancin as well as unnatural (-)-chatancin.
