title: Synthesis of cyclic proline-containing peptides via ring-closing metathesis.
abstract: [reaction: see text] Several dienes embedded in di- and tripeptides which incorporate proline have been prepared and subjected to ring-closing metathesis. Bicyclic peptides of well-defined amide geometry and of varying ring sizes were prepared. Several limitations of the cyclization step were revealed.
