Cyclic tripeptides containing a diphenylether bond of the Chloropeptin left-hand segment were synthesized with the use of TTN phenolic oxidation in high yield. They were found to exist as equilibrium mixtures of two stable conformers caused by a rotation of the amide bond in solution. (C) 1999 Elsevier Science Ltd. All rights reserved.
