Visible light photoredox catalysis enables direct γ- C(sp3)-H alkylation of saturated aliphatic carbonyl compounds. Electron-deficient alkenes are used as the coupling partners in this reaction. Distinguished site selectivity is controlled by the predominant 1,5-hydrogen atom transfer of an amidyl radical generated in situ.

Carboxy marks the spot: A carboxy-directed asymmetric hydrogenation of 1,1-diarylethenes and 1,1-dialkylethenes with chiral iridium/spiro phosphine-oxazoline catalysts has been developed. A wide range of chiral diarylethanes and chiral γ-methyl fatty acids were synthesized with excellent enantioselectivity (see scheme). Copyright
