A protocol for the copper-catalyzed decarboxylative cross-coupling of α‑fluoroacrylic acids with N-tosyl oxaziridines was reported. A series of substituted α-fluoroacrylic acids, and primary, secondary and tertiary substituted oxaziridines were suitable reaction substrates. The decarboxylation reaction exhibited good functional group compatibility and excellent Z-stereoselectivity. This method provides a novel and practical strategy for the construction of monofluoroalkenes, which are key functional groups in the pharmaceutical and material sciences. In addition to α-fluoroacrylic acids, β- fluoroacrylic acid could also participate in the reaction smoothly, which provides a protocol to access various substituted monofluoroalkenes. This methodology also provides a platform for the modification of complex biologically active molecules.

Key words: fluoroacrylic acids, oxaziridines, copper-catalyzed, monofluoroalkene, decarboxylative
