A robust and efficient method for the synthesis of trisubstituted (Z)-chloroalkenes is described. A one-pot reaction of γ,γ-dichloro- α,β-enoyl sultams involving organocuprate-mediated reduction/asymmetric alkylation affords α-chiral (Z)-chloroalkene derivatives in moderate to high yields with excellent diastereoselectivity, and allylic alkylation of internal allylic gem-dichlorides is also demonstrated. This study provides the first examples of the use of allylic gem-dichlorides adjacent to the chiral center for novel 1,4-asymmetric induction.
