Photochemical Metal‐Free Hydrocarbamoylation of Allylamines

Herein, a photoredox‐catalyzed protocol for allylamine hydrocarbamoylation under metal‐free and mild conditions is reported. The proposed method utilizes readily accessible 4‐carboxyamido Hantzsch esters as convenient substrates that deliver carbamoyl radicals upon a visible light‐mediated SET process. Their addition to various allylamines proceeds with good‐to‐excellent efficiency and with high levels of regio‐ and chemoselectivity to provide the corresponding γ‐amino acid amides.
