Significance

A domino Michael addition/sulfur ylide epoxidation has been developed to furnish highly substituted cyclohexadiene epoxides. The reaction can occur inter- or intramolecularly and an asymmetric version is shown using two camphor sulfonium salts. The cyclohexadiene epoxides can be further elaborated to give epoxide ring-opening products in a regioselective manner.
