N-Phthaloyl-L-alanyl-L-phenylalanine methyl ester

A. R. Hayman and J. Simpson

Abstract: The title compound, C₂₁H₂₀N₂O₅, is a terminally protected dipeptide. The backbone adopts an extended conformation, with the phthaloyl group orthogonal to the plane of the trans peptide link. The phenylalanine side chain adopts the g^- conformation. In the crystal lattice, the molecules are stacked with a strong intermolecular hydrogen bond between the H atom of the amide link and the amide carbonyl group of a neighbour.
