Abstract
- 2Phenacylindan1,3dione 3 was treated with Lawessons reagent 2,4bis4methoxyphenyl1,3dithia2,4diphosphetane2,4disulfide to form 2phenyl4Hindeno1,2bthiophene4one 4. Compound 4was subsequently reacted with hydroxyl amine to form the oxime 5, which, upon treatment with polyphosphoric acid, underwent ring expansion Beckmann rearrangement to give 2phenylthieno3,2cquinoline45Hone.
