摘要：

By treatment with BF3-etherate/ethylene glycol, cyclohexanone with a carbonyl function at the 2'- (or 3'-) position of gamma-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).
