A unique reactivity pattern, first observed in the conversion of the marine natural product pestalone into pestalachloride A, was investigated. It was shown that 2-formyl-arylketones smoothly react with ammonia and primary amines, respectively, under mild conditions to afford 3-substituted isoindolinones in high yield. The reaction represents a new option for the derivatization (N-capping) of primary amines. As the substrates are readily accessible the methodology opens a short and modular access to pharmaceutically relevant substituted isoindolinones.
