A practical method for the construction of difluoromethylene-containing 1,4-thiazine moieties using read-ily available diethyl bromodifluoromethanephosphonate(BrCF2PO(OEt)2)as difluorocarbene precusor has been developed.This transformation features the efficient capture of difluorocarbene by pyridinium 1,4-zwitterionic thiolates.A series of structurally novel and functionalized difluoromethylene-containing 1,4-thiazine derivatives were thus synthesized in good yields.
