Abstract
The alpha-allyl-alpha-isopropylglycine derivative, C13H24N2O3, adopts a ful ly extended C-5 conformation. The phi and psi torsion angles are close to t he expected values of 180 degrees. The amide C=O group plays the role of a double acceptor, namely, of an intramolecular hydrogen bond with the uretha ne N-H group, and of an intermolecular hydrogen bond with the amide N-H gro up of a symmetry-related molecule (2 - x, -y, -z).
