A novel transition-metal-free protocol for the synthesis of 1-alkyl-3-(2-oxo-2-aryl/alkyl-ethyl)indolin-2-ones is developed. This work reveals that oxoindole skeletons can be directly constructed from ortho-vinylanilines and commercially available halogenated difluoroalkyl reagents via a C—N cleavage/new C—N bonds and C—C bond formation cascade. This reaction portrays high efficiency and excellent functional group compatibility, and has great potential in the late-stage modifications of pharmaceutical molecules and natural products.

Key words: halo difluoro reagent, 3-substituted 2-oxindole, difluorocarbene
