Anodic olefin couplingreactions using a tosylamine trapping group have been studied. The cyclizations are favored by the use of a less-polar radical cation and more basic reaction conditions. The most significant factor for obtaining good yields of cyclic product is the use of the more basic reaction conditions. However, a number of factors including the nature of both the solvent and the electrolyte

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
