The reaction of α‐lithio allyl aryl sulfides, generated by treatment with n ‐BuLi and chiral ligands at −78°C, with ketones was examined. The α‐addition products were formed in preference to the γ‐addition products. The enantioselectivity of the α‐addition products varied depending on the chiral ligand, and bis(oxazoline)‐ t Bu showed the highest enantioselectivity.
