Visible light-induced synthesis of benzofuro3,2bpyridines from aurone-derived azadienes

JFJiale FanJXJianwei XiePLPing Lu

Key Points

  • The aim is to develop a method for synthesizing benzofuro[3,2b]pyridines from aurone-derived azadienes using visible light.
  • Utilized visible light for the synthesis process
  • Employed a radical dimerization/aromatization mechanism
  • Conducted the reactions under catalyst-free conditions
  • Successfully synthesized benzofuro[3,2b]pyridines regioselectively
  • Intermediates spiro[benzofuran-2,2′benzofuro[3,2-b]pyridines] were observed
  • Demonstrated the viability of radical mechanisms in this reaction context

Abstract

The visible light-induced regioselective synthesis of benzofuro3,2bpyridines from aurone-derived azadienes is achieved through a radical dimerization/aromatization mechanism under catalystfree conditions. In specific instances, spirobenzofuran-2,2′benzofuro[3,2-bpyridines] are formed as intermediates, which can...
