Abstract

A simple and efficient synthesis of 4-halo-3(2H)-furanones by halogenative intramolecular cyclization of sulfonium salts is described, which can expedite the production of a variety of 4-bromo- or 4-iodo-3(2H)-furanones, useful synthetic building blocks, in good to high yield under mild conditions.
