out—it's a trap! The anodiccoupling of olefins with amine trapping groups to form proline and pipecolic acid derivatives with a quaternary α carbon atom (see scheme) was successful despite the significantly lower oxidation potential of the product relative to that of either functional group in the substrate: owing to the very fast cyclization, the oxidation potential of the substrate is lower than that

Recent discoveries that anodic cyclization reactions rely heavily on the success of a second electron oxidation downstream of the cyclization suggest that this second electron oxidation step can be used to channel a reaction down new synthetic pathways. Here we describe one such application that reverses the normal reactivity of an imine group and sets the stage for the asymmetric synthesis of cyclic
