Various 3-(N-substituted amino)-1-isoindolenones were readily synthesized quantitatively by reactions of 2-cyanobenzaldehyde with amines at low temperature such as 20 °C.

Electrochemically initiated tandem reaction between 2-formylbenzonitriles and amines successfully leads toN-Mannich bases of 1-isoindolinones. Enantiopure isoindolinones have been obtained by resolution with chiral amines.
γ-Lactam derivatives are widespread biologically active compounds, covering a large range of activities. Following our interest in both medicinal and green chemistries, we developed an original, cesium salts-mediated, scalable and solvent-free methodology to transform biosourced pyroglutamic acid and itsderivatives to their N,N′-aminals, N,O,N,S-acetals and C5-substituted γ-lactams in good to excellent
