By treatment with BF3-etheratelethylene glycol, cyclohexanone with a carbonyl function at the 2′-(or 3′-) position of γ-side chain underwent novel ring transformation to afford five- (or six-) membered rings, and the fused bicyclic rings (bicyclo[3.3.0]octanone skeleton) were readily converted to bridged bicyclic rings (bicyclo[3.2.1]octene derivative).
通过用BF 3-醚醚乙二醇处理,在γ侧链的2'-(或3'-)位置具有羰基功能的环己酮进行新的环转化,得到五(或六)元环,并且稠合双环(双环[3.3.0]辛烷酮骨架)很容易转化为桥联双环(双环[3.2.1]辛烯衍生物)。
