Abstract
In this work we reported the synthesis of furoquinolinone derivatives as angular furocoumarin analogs by constraction furan ring on benzene moiety of quinolinone. The photooxygenation reaction of synthesized furoquinolnone derivatives was carried out. The photoproducts (o-benzoylhydroxy derivatives) are a convenient intermediate in heteroarene synthesis. Our strategy to synthesize furoquinolinone derivatives is oriented to obtain hydroxyquinolinones followed by Williamson reaction with α-haloketones and finally cyclized to corresponding furoquinolinone derivatives.
