Four amino acid anhydrides were examined using X ray diffraction analysis to determine the intramolecular interactions at atomic resolution. The molecular structures of the Nα-benzyloxycarbonylated anhydrides from Cα,α-disubstituted glycines were compared with that of Ac6c based from their conformations, bond angles and distances. The overall molecular conformations of the acyclic anhydride was shown to occur between the N-H group of one half of the molecule and the phenyl ring of the other half.
