N‐Acylated Benzylic Amines via Photocatalytic Hydroarylation of Enamides

Abstract

AbstractPhotocatalytic conditions are reported for hydroarylation of enamides, a reaction that provides benzylic amine structures of importance in synthetic and medicinal chemistry. Hydroarylation of enamides occurs under catalysis by Ru(bpy)3(PF6)2 with blue LED light; versatility is demonstrated by successful hydroarylations with substituents connected via the alkene and amide linkages of the enamide. Electron‐rich arenes and heteroarenes including 1,3,5‐trimethoxybenzene, 2‐naphthol, 2‐methylfuran, pyrrole, and substituted indoles are accommodated.
