Intermolecular aminotrifluoromethylation of alkenes catalyzed by [Ru(bpy)3]2þ
under visible light irradiation has been explored. The present
photocatalytic protocol achieves highly efficient and regioselective difunctionalization of CdC bonds, leading to a variety of β-trifluoromethylamines.
The reaction is applied to “late-stage aminotrifluoromethylation” of steroid and amino acid scaffolds.
