A diastereoselective and concise synthesis of functionalised vinyl epoxides with a Morita–Baylis–Hillman backbone

Abstract

A highly diastereoselective organocatalytic synthesis of unique functionalised vinyl epoxides, displaying a Morita–Baylis–Hillman backbone, has been developed by means of an user friendly sulfonium ylide epoxidation of aldehydes from a readily available α-(bromomethyl)acrylamide derivative. The first result in the asymmetric version is discussed.
