for the synthesis of amides and peptides is reported. Synergistic cooperation between a cobaloxime and a photoredox catalyst removes the elements of H2O through the use of PPh3 as a gentle organic reductant. The deoxygenative method is compatible with gram-scale peptide synthesis and applicable to peptide fragment condensation and SPPS, which may find applications in both organic synthesis and pharmaceutical
