(+)-8-O-acetyl-1,2,11,13-tetrahydro-8-epi -vernolepin (11) was synthesized from salonitenolide (4). The key steps were the Cope rearrangement of the germacradiene skeleton to elemadiene and the long-range functionalization at C-14, which allows the intramolecular cyclisation necessary for the formation of the δ-lactone ring of 11.
由红salon内酯(4)合成了(+)-8-O-乙酰基-1,2,11,13-四氢-8-表位-藜芦醇(11)。关键步骤是胚芽骨架的Cope重排至榄香烯和在C-14处的远程官能化,这允许形成11的δ-内酯环所需的分子内环化。
