  Assembly of 4-Aminoquinolines via Palladium Catalysis:  A Mild and Convenient Alternative to S_NAr Methodology

  摘要：

  4-Aminoquinolines, classically prepared via SNAr chemistry from an amine and 4-haloquinoline, are important scaffolds in medicinal chemistry. Interest in these compounds prompted us to explore palladium catalysis as an alternative to the existing methods for their preparation. Initial results followed by an iterative screening paradigm confirmed Pd(OAc)(2)/ DPEphos/K3PO4 as a mild and convenient alternative for the formation of the C-N bond in 4-aminoquinolines. A description of the screen and the scope of this methodology are discussed herein.

  An efficient method for visible-light-induced perfluoroalkylaion of quinolin-4-ol has been reported. In the presence of t-BuONa and perfluoroalkyl iodide, quinolin-4-ol underwent CH perfluoroalkylation under the irradiation of green light. Mechanistic studies demonstrated that visible-light promoted intermolecular charge transfer within the transient electron donor-acceptor complex in the absence of
