                                    Reactions of gamma-activated-alpha,beta-unsaturated lactams with allylboronate in the presence of LiOi-Pr and CuX (stoichiometric or catalytic amount) proceed in an anti-S(N)2' manner to yield alpha-allylated compounds that serve as a potential synthetic intermediate for cis-aminoacyl-Pro mimetics.
