Silver-Catalyzed Carbocyclization of Azide-Tethered Alkynes: Expeditious Synthesis of Polysubstituted Quinolines

10.1002/adsc.201801425

The research aims to develop an efficient method for synthesizing polysubstituted quinolines using a silver-catalyzed carbocyclization reaction. The study focuses on the use of azide-tethered alkynes as substrates and employs silver catalysts, specifically AgSbF6, to facilitate the 6-endo-dig cyclization process. The reaction involves the formation of an α-imino carbene intermediate, which is subsequently intercepted by external halides (R-X, where X = Cl, Br, or I) through a ylide intermediate, leading to the formation of quinoline frameworks. The key findings include the successful synthesis of quinolines with good to high yields under mild reaction conditions, demonstrating the method's efficiency and practicality. The study also highlights the versatility of the method by showing its applicability to various substituted aromatic nuclei and different halides. Additionally, the synthesized quinolines were further transformed into more complex structures, such as dihydrofuroquinolines and tetracyclic compounds, showcasing the potential for further chemical modifications. The research concludes that the silver-catalyzed approach provides a straightforward and efficient route for the synthesis of polysubstituted quinolines, which are valuable heterocyclic motifs in various biologically active molecules.
