A concise and efficient synthesis of the C13 tricyclic core of the dihydro-β-agarofuran skeleton common to the natural Celastraceae sesquiterpenoids is described. The strategy entails a Mukaiyama aldol reaction of a tetrahydronaphthalene enol silane with acetone, epoxidation, ketone reduction, and acid-catalyzed cyclization. This key scaffold was converted into diverse polyhydroxylated derivatives
描述了一种简明有效的合成天然Celastraceae倍半萜类化合物所共有的二氢-β-agarofuran骨架的C 13三环核心的方法。该策略涉及四氢萘烯醇硅烷与丙酮的Mukaiyama羟醛反应,环氧化,酮还原和酸催化的环化反应。该关键支架被转化为多种多羟基化衍生物,并对其杀虫活性进行了测试。
