Abstract

The peptide N-benzyloxycarbonyl-L-valyl-L-tyrosine methyl ester or NCbz-Val-Tyr-OMe (where NCbz is N-benzyloxycarbonyl and OMe indicates the methyl ester), C23H28N2O6, has an extended backbone conformation. The aromatic rings of the Tyr residue and the NCbz group are involved in various attractive intra- and intermolecular aromatic - interactions which stabilize the conformation and packing in the crystal structure, in addition to NH...O and OH...O hydrogen bonds. The aromatic - interactions include parallel-displaced, perpendicular T-shaped, perpendicular L-shaped and inclined orientations.
