The synthesis of branched peptides from cyanomethylenamino pseudopeptides, via catalytic hydrogenation in the presence of amino acid derivatives, is described. When the inserted amino acid was a glycine derivative, the resulting branched peptide lactamized in situ to 2-oxopiperazine derivatives. This new C-backbone peptide branching approach is compatible with the diversity of amino acid side chains
