## Abstract The conformational behavior of the title compounds has been investigated by Hartree–Fock, MP2, and DFT computations on the most significant structures related to variations of the backbone dihedral angles, cis/trans isomerism around the peptide bond, and diastereoisomeric puckering of t

The cyclic hexapeptide cycle[ -Pro'-Gly2-Glu3 (OBzl) -Pro4-Phe5-Leu6-] ( 1 ; OBzl: benzyl ester) was modeled and synthesized to be used as a chiral site for the separation of enantiomers. Total correlation spectroscopy and nuclear Ovehauser effect spectroscopy spectra of the peptide in CDCIB showed
