The intramolecular addition reaction of metal enolates of ketones to oxiranes has been applied to a series of epoxy ketones derivedfrom cyclohexene oxide. γ-Hydroxy ketones (γ-HKs, C-alkylation products) or hydroxy enol ethers (HEEs, O-alkylation products) are obtained, depending on the nature of the cyclic transition state in each case involved and the application of the Fürst–Plattner rule. The
