An enantioselective and highly diastereoselective bromoetherification and desymmetrization of olefinic 1,3-diols has been developed using a C-2-symmetric cyclic sulfide catalyst. This methodology has been successfully applied to the synthesis of the key intermediate of an orally active antifungal drug posaconazole (Noxafil).
