Abstract :
The synthesis and crystal structure of peptide 6,6′-dimethyl biphenyl hybrid are described. The title compound was synthesized by reaction between 6,6′-dimethyl-[1,1′-biphenyl]-2,2′-dicarbonyl dichloride in CH2Cl2, amine HN–proline–phenylalanine–alanine–COOMe and Et3N at 273 K under N2 atmosphere and characterized by single-crystal X-ray diffraction. The asymmetric unit contains one peptide molecule and a quarter of a water molecule. A disorder of a methyl and methoxycarbonyl group of one alanine residue is observed with occupancy ratio 0.502 (6):0.498 (6). The structure is consolidated by intra- and intermolecular hydrogen bonds.
