A novel synthesis of (± )-Vernolepin (1) is described. A suitably substituted cis-fused 2-oxa-3-decalone precursor (29) has been constructed starting from 2,5-cyclohexadiene carboxylic acid via an intramolecular cyclopropanation reaction (23 to 18). The route culminated in the synthesis of Grieco's lactone (53) which has previously been converted to (± )-vernolepin (1) and (± )-vernomenin (2).
描述了一种新的(±)-Vernolepin(1)的合成方法。从2,5-环己二烯羧酸开始,通过分子内环丙烷化反应(23至18),构建了适当取代的顺式稠合的2-氧杂-3-癸酮的前体(29)。该路线最终合成了Grieco的内酯(53),该内酯先前已被转化为(±)-藜芦醇(1)和(±)-藜芦醇(2)。
