  4. Abstract:
  5. A one-pot synthesis of functionalized benzo thiazine derivatives via a Cu-catalyzed, multicomponent reaction of isocyanides, aniline, and heterocumulenes in acetonitrile at room temperature was developed. Transition metal-catalyzed activation of C-H bonds under mild copper-catalytic reaction conditions, using simple and available starting materials, also obtaining a pure product with high yield without applying column chromatography are the major advantages of the applied method among the other ones used for this purpose. The structures are confirmed spectroscopically (1H- and 13C-NMR, IR, and EI-MS) and through elemental analyses. © 2019 The Chemical Society Located in Taipei & Wiley-VCH Verlag GmbH & Co.
