Ring expansion reaction of a substituted cyclobutanone with CH2I2 and SmI2 proceeded cleanly in extended reaction time (15 h) to afford the corresponding cyclopentanone in good yield, whereas short reaction time (0.5 h) pr

The esters of cis-bicyclononenols, exo- and endo-brexan-5-ols, and exo-brendan-2-ol were obtained by the addition of formic, acetic, and trifluoroacetic acids to cis-bicyclonona-3,7-diene.The composition of the reaction products and its dependence on the reaction conditions were determined.A method is proposed for the separation of the bicyclic and tricyclic components.The mechanism of the transannular cyclization is discussed.
