Direct sp³ CH Amination of Nitrogen‐Containing Benzoheterocycles Mediated by Visible‐Light‐Photoredox Catalysts

Visible-light-mediated direct sp(3) C-H amination of benzocyclic amines via α-aminoalkyl radicals by using photoredox catalysts is described here. The obtained N,N-acetals were also successfully applied for carbon-carbon bond forming reactions with carbon nucleophiles. The procedure is suitable for a late-stage modification of C-H bonds to C-C bonds.
