Visible‐Light‐Promoted Intermolecular Oxidative Dearomatization of β‐Naphthols with <i>N</i>‐Hydroxycarbamates

Abstract

Abstract An intermolecular oxidative dearomatization of β‐naphthols with N ‐hydroxycarbamates promoted by visible light was realized by means of photogenerated β‐naphthol radical cation intermediates. With a commercially available organic dye, the naphthalenones bearing a fully substituted stereogenic center were obtained with up to 92 % yield under aerobic conditions (26 examples). In addition, the rearrangement of C−O coupling products to C−N coupling compounds could be achieved merely in the presence of Cs 2 CO 3 . This transformation simultaneously provides an attractive and synthetically useful approach to access the aminative dearomatization compounds.
