The radical addition-transfer of S-(2-fluoro-phenacyl)xanthates can be used to construct rapidly benzothiepinones, including libraries of complex aza-bridged derivatives, and highly functionalized 2,3-dihydrothieno[2,3-b] thiopyran-4-ones.
An unusual and highly efficient access to thieno[2,3-b]-benzothiopyran structures

Dihydrothieno[2,3-b]-benzothiopyran-4-ones are easily obtained by an intermolecular radical addition to an unactivated olefin using an S-o- fluorophenacyl xanthate followed by a novel, base induced domino cyclisation.
