Cyclic peptides, which often exhibit interesting biological properties, can be obtained by macrolactamization of adequately protected linear peptide chains. Because of the remarkable biological properties, methods for the efficient cyclization of peptides are of high interest. We herein describe three different protocols for the cyclization of peptides and depsipeptides via amide bond formation. These methods can, in principal, be applied to any linear peptide chain.
