Epoxyalkylcopper compounds have readily been prepared by the directoxidativeaddition of active copper to epoxyalkyl halides. The intramolecular cyclization of the epoxyalkylcopper reagents via an epoxide cleavage process is described. Significantly, many functional groups can be present in the bromoepoxides yielding highly functionalized carbocycles. The regioselectivity of this cyclization is affected
