The indoline skeleton is widely present in natural products, drugs and bioactive molecules. Introducing monofluoroalkenes into indoline is expected to develop products with medicinal value. However, the current research is only limited to the introduction of monofluoroalkenes to the highly reactive C2 position of indole compounds through transition- metal-catalyzed, and the monofluoroalkenylation at the less reactive C7 position has not been reported. Functionalization/ oxidation of the C7—H bond of indolines is an effective strategy for obtaining C7-functionalized indoles. Based on this, a novel ruthenium(II)-catalyzed C7—H monofluoroalkenylation of indolines with gem-difluorostyrenes was developed. The protocol exhibited good functional group tolerance, excellent configuration exclusivity and site selectivity. In addition, the method was scale-up implementability and could efficiently obtain indole derivatives through oxidation, which offers a potential synthetic route for this structure.

Key words: ruthenium(II)-catalyzed, indolines, gem-difluorostyrenes, C7—H monofluoroalkenylation, configuration exclusivity
