标题：palladium-catalyzed dimerization of n-aryl propargylamines for the synthesis of 3-vinylquinolines
abstact：a straightforward method for the synthesis of polyfunctionalized quinolines from readily available n-aryl propargylamines under aerobic conditions was developed. it provides convenient access to a variety of synthetically and pharmaceutically important quinolines in moderate to good yields. control experiments suggest that the cascade reaction might proceed via the pd-catalyzed electrophilic cyclization of n-aryl propargylamines followed by a hydroarylation process through trapping of the σ-quinolinylpalladium intermediate with a second molecule of the substrate.
