CH/CN activation: The first palladium/copper‐catalyzed aerobic oxidative CH alkenylation/N‐dealkylative carbonylation of tertiary anilines has been developed. Various functional groups were tolerated and acrylic ester could also be suitable substrates. This transformation provided efficient and straightforward synthesis of biologically active 3‐methyleneindolin‐2‐one derivatives from cheap and simple

One-Step Synthesis of Highly Functionalized Monofluorinated Cyclopropanes from Electron-Deficient Alkenes
The unique combination of Zn/LiCl allowed generation of reactive zinc enolate from ethyl dibromofluoroacetate. This fluorinated enolate reacts efficiently with a wide range of functionalized electron-deficient alkenes to afford the corresponding monofluorinated cyclopropylcarboxylates in good yields.

paramount. In this study, we combined scaffold-directed synthesis with a hybrid experimental and transcriptomeanalysis to identify bis-spirooxindole cyclopropanes that inhibit cancer cell proliferation through disruption of ribosomal function. These findings demonstrate the value of an integrated, biologically inspired synthesis and assay strategy for the accelerated identification of first-in-class
