Significance

Asymmetric transition-metal-­catalyzed allylic substitutions are powerful synthetic transformations for the preparation of chiral allylic substrates. Herein, an iridium-catalyzed enantioselective allylation protocol using sodium thio­phenoxide 1 as a nucleophile has been developed. The best selectivities could be achieved with the chiral monodentate phosphoramidite ligand L*(S,S,S a )-5 and CsF as an additive in dichloromethane.
