摘要：

The small synthetic peptide, benzyl 2-(tert-butoxycarbonylamino)isobutyrate, C16H23NO4, has the alpha -helical conformation [\ phi \ = 55.8 (2)degrees and \ psi \ = 37.9 (2)degrees] observed in peptide fragments of peptaibols containing the alpha -aminoisobutyric acid (Aib) residue. The structure shows no intramolecular hydrogen bonding, which would disrupt the limited conformational freedom associated with this amino acid. Two weak intermolecular hydrogen contacts are observed.
