Visible-light-induced selective amination of enol ethers with N-alkoxyamides by using DDQ as a photoredox catalyst

Nitrogen-centered radical (NCR) mediated amination of enol ethers has been developed under visible-light irradiation and metal-free conditions. In the presence of commercially available DDQ as a photoredox catalyst, the reactions of a variety of N-alkoxyamides with enol ethers undergo smoothly to deliver the corresponding N-alkyl products in good yields at room temperature.
