2-Bromobenzaldehyde is carbonylativelycyclized with primary amines under carbon monoxide pressure in DMF at 100 °C in the presence of a catalytic amount of a palladium catalyst to give the corresponding isoindolin-1-ones in moderate to high yields.

A facile and efficient method for the synthesis of N-substituted isoindolin-1-one derivatives from 2-formylbenzoic acid and amine under Pd(OAc)2/HCOOH system has been described. The whole process is carried out in ligand-free conditions and furnished the desired products by reductive intramolecular cyclization. Furthermore, this procedure is applied successfully for the modification of natural products
Application of the Mild-Condition Phthalimidine Synthesis with Use of 1,2,3-1H-Benzotriazole and 2-Mercaptoethanol as Dual Synthetic Auxiliaries. Effective Synthesis of Phthalimidines Possessing a Variety of Substituents at 2-Position
The mild-condition phthalimidine synthesis based on Mannich type 1:1 condensation reaction between o-phthalaldehyde with a variety of primary amines in the presence of excess 2-mercaptoethanol and 1,2,3-1H-benzotriazole as "dual synthetic auxiliaries" in MeCN for 13 h at room temperature afford 2-substituted phthalimidines (2,3-dihydroisoindol-1-one) in fair to good isolated yields.
