A short enantioselective synthesis of 6-substituted cis-2,8-dioxabicyclo[3.3.0]octan-3-ones is described. The pivotal step is coupling of a tertiary radical generated directly from a tertiary alcohol with a 3-chloro-5-alkoxybutenolide. This strategy is applied toward scalable 14-15 step syntheses of three rearranged spongian diterpenoids: cheloviolenes A and B and dendrillolide C.
本文描述了一种 6-取代的顺式-2,8-二氧杂双环[3.3.0]辛烷-3-酮的短对映选择性合成方法。关键步骤是直接从叔醇生成的叔自由基与 3-氯-5-烷氧基丁烯内酯的偶联。该策略应用于三个重排海绵二萜类化合物（cheloviolenes A 和 B 以及 dendrillolide C）的 14-15 步规模化合成。
