Asymmetric alkylation of remote C(sp 3 )-H bonds by combining proton-coupled electron transfer with chiral Lewis acid catalysis.

The catalytic asymmetric alkylation of the remote, unactivated δ-position of N-alkyl amides was enabled by the combination of visible-light-induced proton-coupled electron transfer, 1,5-hydrogen atom transfer, and chiral Lewis acid catalysis in up to 82% yield and up to 97% ee.
