In this article we describe a series of newasymmetric Michael reactions of carboxylate-3-substituted isoindolinones used as nucleophiles in the synthesis of valuable chiral tetrasubstituted derivatives. It has been shown that the reactivity and enantioselectivity strongly depend on the substitution pattern of the isoindolinone, requiring either cinchona-alkaloid based phase transfer catalysts or bifunctional
