Some procedures for a benzofuroisoquinolinone 1 were studied. Its O-analogous benzofuroisocoumarin 2 was synthesized from methyl salicylate with diethyl α-bromohomophthalate (9). And, the benzofuroisoquinolinone 1 was obtained by treating 2 with ammonia gas in a sealed tube.
An Unexpected Rearrangement of 2-(2-Benzofuranyl)-benzonitriles: a New Route to Phenylmethylene-dihydro-isoindolinones
Guillaumel, Jean,Boccara, Nicole,Demerseman, Pierre,Royer, Rene
, p. 1604 - 1605 (2007/10/02)
Depending on the solvent used, the alkaline hydrolysis of 2-(2-benzofuranyl)-benzonitriles leads to the expected amide or acid, or to isoindolinones by rearrangement.
