Crystal structure of (3R)-3-benzyl-4-[(tert-butoxycarbonyl)amino]butanoic acid

Abstract

The characteristic feature of the title molecule, C16H23NO4, is the syn configuration of the partially double amide C—N bond [C—N—C—O torsion angle = −14.8 (2)°]. The crystal packing is determined by intermolecular O—H...O and N—H...O hydrogen bonds, which link the molecules into a double-chain structure extending along [010].
