英文摘要：

The recent progress in transition metal-catalyzed asymmetric ring-opening reactions of oxa（aza）bicyclic alkenes with carbanion nucleophiles is reviewed with focus on the influence of the types of transition metal catalysts, carbanion nucleophiles, ligands, the structures of oxa（aza）bicyclic alkenes, solvents and additives on the asymmetric ring-opening reactions. Moreover, the parties of possible mechanisms for the asymmetric ring-opening reactions are also discussed.
