Lithium enolates, generated by deprotonation of ketones with lithium diisopropylamide, react with diiodomethane in the presence of SmI2 to give cyclopropanols.
Peroxidated compounds were prepared by treatment of ether solutions of bicyclo[n.1.0]alkanols with oxygen in the presence of silica gel, ferric acetylacetonate and light.
