Synthesis of cyclic peptides and peptidomimetics by metathesis reactions

This review surveys developments in the field of ring-closing metathesis and cross-metathesis reactions applied to the synthesis of constrained amino acids, peptides, and peptidomimetics. Examples, in which metathesis is used as one of the synthetic tools to arrive at the desired peptide molecules as well as examples that describe in-depth optimized metathesis protocols, will be discussed. Currently, metathesis reactions are well-accepted synthetic tools within the field of peptide chemistry and provide peptides unprecedented properties like conformational, metabolic, and chemical stability and improved bioactivity
