Methyl N-(tert-Butoxycarbonyl)glycyl-L-valyl-L-tryptophanate

The title compound, C₂₄H₃₄N₄O₆, is an end-protected tripeptide and the peptide backbone adopts an extended conformation. The peptide units are trans and show significant deviations from planarity. The crystal packing enables neighbouring molecules to interact through an anti­parallel β-sheet arrangement. An intramolecular hydrogen bond occurs between the peptide backbone carbonyl group and the N atom in the tryptophan side chain. An interesting feature of the packing is that the tryptophan side chain straddles both hydrophobic and hydrophilic environments.
