We herein report a strategy to first form an intermediate with an adjacent, redox versatile SeN bond which undergoes two successive sigmatropic rearrangements to generate the para -amination product and regenerate the selenium catalyst (Fig
Through a series of enzyme-driven reactions, Phase 1 alters the structure of toxins via: Oxidation introducing oxygen to increase chemical reactivity Reduction removing oxygen to alter molecular configuration Hydrolysis breaking chemical bonds using water Hydration adding water molecules to facilitate further processing Dehalogenation removing halogen atoms such as chlorine or bromine The purpose of Phase 1 is not elimination, but activation
