While the use of nitrones as dipolar cycloaddition reagents and N-hydroxyamines as heterocyclic precursors is well-established, the breadth of pericyclic reactions where these compounds can be applied has been limited by the dearth of methods available to access alkenyl-substituted derivatives. Our laboratory has demonstrated that copper-promoted alkenylation reactions can be tuned for the synthesis of N-alkenylnitrones and N,O-dialkenylhydroxylamines.1,2 These tools have allowed us to investigate the reactivity of these novel reactive intermediates in electrocyclization processes and [3,3]-sigmatropic rearrangement cascade reactions, respectively.2-4 The scope these new methods, our understanding of these processes, and the chemical diversity that can be rapidly achieved using these transformations will be discussed.
