Tricyclic compound 3 was synthesized via a cyclopropanation reaction promoted by [Rh(OAc)2]2. This highly strained compound was found to undergo selective chemical transformations to give [2.2.2] oxa-bicyclic ketones. This methodology was applied in a total synthesis of the monoterpene, eucalyptol.
