Anthranils, 7-acetyl-, rearrangement

S-Formylbenzofuroxan has been prepared, but the 4-acetyl compound rearranges under the conditions used for its jDreparation, to an anthranil derivative (see Section VIII). [Pg.20]

The phenyl anthranilates (313) and their N-acetyl derivatives undergo photo-Fries rearrangement to (314) and the products have been used as precursors for the synthesis of hetero-... [Pg.245]

A photocyclisation related to that well established for dienones has been reported in the 2-benzoylquinoxaline (39) and yields the purple-coloured methylindoloquinoxallne (40). Synthetically useful benzophenone derivatives (41) have been prepared by photo-Fries rearrangement of the anthranilates (42), and a detailed study of the same photorearrangement in W-acetyl-carbazole has been described. ...
