Abstract
A practical, efficient approach for the synthesis of C4-arylated 2-quinolones from propargylic chlorides and anilines has been developed. The synthesis process involves subsequent oxidations of the initial products, tetrahydroquinolines and quinolinium ions, eventually leading to desired quinolones. A mechanism for the transformation is proposed based on a meticulous examination of intermediates and comprehensive control experiments. With a thorough understanding of the reaction mechanism, the applicability of the reaction scope is expanded.
期刊介绍:
Helvetica Chimica Acta, founded by the Swiss Chemical Society in 1917, is a monthly multidisciplinary journal dedicated to the dissemination of knowledge in all disciplines of chemistry (organic, inorganic, physical, technical, theoretical and analytical chemistry) as well as research at the interface with other sciences, where molecular aspects are key to the findings. Helvetica Chimica Acta is committed to the publication of original, high quality papers at the frontier of scientific research. All contributions will be peer reviewed with the highest possible standards and published within 3 months of receipt, with no restriction on the length of the papers and in full color.
