  Synthesis of 2-Benzoylfuro[2,3-b]Quinolines from Quinoline-Based Chalcones

  摘要：

  We have described an elegant synthesis of 2-benzoylfuro[2,3-b]quinolines from quinolinyl chalcones via bromination and epoxidation. Interestingly, we found that during the bromination, the chalcones were cyclized to gave monobromodihydrofuroquinolines, which were dehydrobrominated with 1,8-diazabicyclo[5,4,0]undec-7-ene. During the epoxidation, chalcones were not cyclized and gave epoxides, which were treated with polyphosphoric acid to give the title compound. We have differentiated the addition of bromine and urea hydrogen peroxide to alpha,beta-unsaturated carbonyl of quinolinyl chalcones by this new mechanism.
