N-Benzyl-N-(tert-butyloxycarbonyl)glycine, an N-Substituted Glycine (Peptoid) Monomer

The title compound, C₁₄H₁₉NO₄, an amino acid mimic, was crystallized from ethyl acetate solution in a centrosymmetric space group. The distance between the side chain and the backbone was shorter than usually found in amino acids. The positional shift from [alpha]-carbon to nitrogen produced no significant steric hindrance between the side chain and the tert-butyl group.
