A New Alkaline Rearrangement of the Benzofuran Skeleton. One Step Transformation of 2-(2-Benzofuranyl)benzonitriles Into (Z)-Phenylmethyleneisoindolinones

The alkaline hydrolysis of 2-(2-benzofuranyl)benzonitriles 2 by potassium hydroxide under reflux in ethanol stops at the corresponding amides 5.Using other solvents (ethylene glycol or methoxyethanol) at higher temperatures, one can obtain either the amides 5, the acids 1 or rearrangement products depending on the experimental conditions.The rearrangement products were identified as (Z)-phenylmethylenedihydroisoindolinones 6 resulting from opening of the furan ring.The structures of the compounds 6 were established by 1H nmr spectroscopy (nOe) and X-ray crystallography.
