The recent emergence of biological activities of chiral 3-substituted-3-hydroxy-2-oxindoles has inspired synthetic chemists to develop new methodologies for their synthesis. Both chiral organocatalysts and organometallic catalysts have provided an important platform for their synthesis and in recent years, great achievements have been made in their catalytic asymmetric synthesis. This review summarizes the catalytic strategies for enantioselective synthesis of targeted frameworks.
