A green and sustainable visible light-induced triphenylphosphine-promoted deoxygenation strategy to generate acyl radicals from commercially available amino acids has been developed. A wide range of dipeptides, amides and esters were obtained in good yields (77-94%) without epimerization. The strategy has advantages of short reaction time, not requiring dry solvent or inert atmosphere, operationally simple conditions, broad substrate scope, good functionals tolerance.
