A convenient one-pot synthesis of 3-substituted isoindolinones were reported in good yield via Pinner-Dimroth tandem reaction of 1,3-dicarbonyl compounds and 2-cyanobenzaldehyde in the catalysis of CoCl2 center dot 6H(2)O. This method has advantages of time efficiency and mild reaction conditions.

isoindolinones toward Cu(II), Fe(III), Al(III), and Zn(II) salts has been highlighted by UV–vis spectroscopic studies. Conversely, heterocyclicanalogs substituted with dimethyl malonate showed no complexing ability. Further insights have been given by the determination of equilibrium constants and distribution diagram, while the synthesis, isolation, and characterization of Cu(II)-β-diketonate-isoindolinone

The aldol addition of readily enolizable 1,3-dicarbonyl compounds to 2-cyanobenzaldehyde in the presence of a tertiary amine led to a series of new 3-substituted isoindolinones. Despite the instability of the related aldols, this synthesis was possible because of the intramolecular trapping of the adducts with the cyano group due to a tandem process of cyclization and rearrangement. Simple decarboxylation of some derivatives gave access to very useful compounds.
