  Pd-Catalyzed Dearboxylative Heck Coupling with Dioxygen as the Terminal Oxidant

  摘要：

  Pd-catalyzed decarboxylative Heck coupling of aromatic carboxylic acids with various olefins is developed using O-2 as the terminal oxidant. Enhancement of O-2 pressure leads to improving reaction turnover in this transformation and allows significantly reducing catalyst loading for efficient conversion of electron-rich benzoic acids. A Pd catalyst supported by a carbene ligand enables using electron-deficient benzoic acids as coupling partners.

  Several new (E) stilbenes were synthesized by a combination of a Wittig olefination followed by Mizoroki-Heck coupling reactions. These compounds were screened for antitumor activity in a panel of 8 human cancer cell lines by a colorimetric SRB assay. Several of these compounds exhibit strong cytotoxicity. The most active compound of this series showed an average IC50 value of 0.03 mu mol; it acts by apoptosis as shown by a dye-exclusion test, an extra acridine orange/ethidium bromide staining and DNA-laddering experiments.
