Abstract

Synthesis of 4,8,9-trimethylfuro[2,3-h]quinolin-2(1H)-one as angular furoquinolinone (psoralen analog) was carried out through Williamson reaction of 7-hydroxy-4-methyl-2H-quinolin-2-one with 3 chloro-2-butanone followed by cyclization with polyphosphoric acid (PPA).o- Benzoylhydroxy derivative of quinolinone was prepared through the photooxygenation and Fries rearrangement.
