The reductive coupling of phthalimides with ketones and aldehydes by Zn-TiCl4 in THF gave two- and four-electron reduced products, 3-hydroxy-3-(1-hydroxyalkyl)isoindolin-1-ones and alkylideneisoindolin-1-ones, selectively by controlling the rea

A series of Z-configured (hetero)aryl and alkylmethylideneisoindolin-1-ones has been efficiently prepared by treatment of N-methoxycarbonylisoindolin-1- ones with a base and reaction with selected aldehydes. The parent N-acylated isoindolin-1-ones have be

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.
