title: Crystal structure of (3R)-3-benzyl-4-[(tert-but-oxy-carbon-yl)amino]-butanoic acid.
abstract: The characteristic feature of the title mol-ecule, 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 inter-molecular O-H⋯O and N-H⋯O hydrogen bonds, which link the mol-ecules into a double-chain structure extending along [010].
