A simple and efficient one-pot synthesis of 2,3-disubstituted isoindolinones via the reaction of o-lithiated aromaticimines with carbon monoxide under one atmospheric pressure has been developed. Preliminary in vitro tests for fungicidal activity of these isoindolinone derivatives have been carried out, indicating that most of them exhibit good fungicidal activities.
This communication describes a method for the Ni(cod)(2)-mediated intramolecular arylation of alkyl C-H bonds adjacent to the nitrogen atom in benzamide substrates. The transformation proceeds at room temperature and exhibits selectivity for functionalization of more substituted C-H bonds. The yields of the desired isoindolinone products are higher with benzamide substrates containing tertiary alkyl groups on the nitrogen atom than with those bearing primary or secondary alkyls. The results described herein suggest a mechanism involving radical intermediates for these reactions.
