Abstract
An unusual nucleophilic conjugate addition of organocuprates to enynedioates resulted in chemo- and regioselective formation of β(γ′)-addition products, rather than α(δ′)-addition products, in moderate to good yields. This addition pattern is different from that with organophosphanes or alkyl amines, and presents a short and efficient method for the preparation of various β(γ′)-alkyl- or -aryl-substituted muconates compared with other synthetic approaches.
