Abnormal Beckmann fragmentation of Hajos ketone oxime regioselectively forms of a chiral 1-oxygenated 2,2-dimethyl-4-methylene-cyclohexan skeleton. Using this transformation as a key step, the total synthesis of (−)-elegansidiol, an oxygenated mono-carbocyclic sesquiterpenoid, was achieved.
Hajos酮肟的贝克曼片段异常选择性地形成手性的1-氧化的2,2-二甲基-4-亚甲基-环己酮骨架。使用该转变作为关键步骤,可以实现含氧单碳杂环倍半萜烯-(-)-elegansidiol的全合成。
