The reactivity of the tricyclic enone, (+)-(1S, 2R, 4R, 7R)-3, 3, 7-trimethyltricyclo[6.3.0.02, 4]undec-8-en-10-one(1), obtained previously as the key intermediate for the synthesis of compounds bearing the aromadendrane uncleus was investigated, and a natural aromadendrane-type sesquiterpene, (+)-1, 2-didehydroaromadendrane (2), was synthesized via regio- and stereo-specific introduction of a methyl group at the C-11 position of 1 followed by reductive deoxygenation.
对之前作为合成芳香树烷关键中间体的三环烯酮((+)-(1S, 2R, 4R, 7R)-3, 3, 7-trimethyltricyclo[6.3.0.02, 4]undec-8-en-10-one(1))的反应性进行了研究,并通过在1的C-11位引入甲基,然后进行还原脱氧,合成了天然芳香树烷型倍半萜((+)-1, 2-didehydroaromadendrane (2))。
