To address the shortcomings in the application of bioactive peptides as drugs, incorporation of unnatural amino acids (UAAs) has been used. Here, the authors report an ionic compound-promoted C-N cleavage of alkyl pyridinium to generate alkyl radicals upon excitation by visible light, and apply it for deaminative hydroalkylation of alkenes to synthesise diverse β-alkyl substituted UAAs.
