describe a synthetic approach to sterically hindered α-hydroxy carbonyl compounds through radical–radical coupling. An organic photoredox catalysis reaction converts an aliphatic carboxylic acid and α-ketocarbonyl to a transient alkyl radical and a persistent ketyl radical, respectively, which couple selectively based on the persistent radical effect. This protocol allows the use of primary, secondary, and
