Iridium-catalyzed asymmetric allylic substitution reaction is one of the most important methods for the synthesis of chiral compounds. The recent research progress in iridium-catalyzed asymmetric allylic substitution reactions of allylic ester and its derivatives is reviewed with focus on the influences of the iridium catalysts, the substrate structures of allylic ester and its derivatives, the type of nucleophiles, the effects of solvents and additives on asymmetric substitution reaction. Moreover, the possible mechanisms are also discussed in this review.
