The first total synthesis of a polypeptin, PE2, as well as the solution structure is reported. Synthesis in optically pure form confirms the proposed stereochemistry for the polypeptins at the 3-position on the 3-hydroxy depsipeptide moiety. We have also determined the NMR structure of PE2 in aqueous solution, showing it to form a stable ring conformation. The synthetic peptide shows anti-bacterial activity consistent with reports for naturally derived counterparts.
