Facile Synthesis of Cyclic Tetrapeptides from Nonactivated Peptide Esters on Metal Centers.

Abstract

The cyclization of dipeptide esters of α-, β-, γ-, and δ-amino acids can be achieved by using NiII , PdII , or CuII templates. The structure of one of the complexes (1) obtained, which was determined by X-ray crystallography, reveals that the anions form layers and are linked to water molecules by hydrogen bonds. © 1998 WILEY-VCH Verlag GmbH, Weinheim, Fed.
