Asymmetric intramolecular aza-Michael reactions catalyzed by cinchoninium phase-transfer organocatalysts are used for the synthesis of optically active isoindolinones. Selected oligomeric cinchoninium salts are efficient and selective catalysts for the intramolecular addition of alkenylated benzamide substrates. The resulting compounds are useful intermediates for the synthesis and development of
