Enantioselective iridium-catalyzed allylation of sodium benzotriazolide: an efficient way to chiral allylbenzotriazoles

A highly enantioselective allylic substitution of sodium benzotriazolide has been attained in the presence of [Ir(COD)Cl](2)/phosphoramidite ligand L1 together with K3PO4 as an additive, producing enantioen-riched allylbenzotriazole compounds with up to 98% ee.
