Abstract
The title compounds, C19H21NO3 and C31H29NO3, are derivatives of α-aminoisobutyric acid, with benzyl and dibenzyl substitution. The pseudo-peptide formed by the N-formyl and ethyl ester substitution at the Cα position switches from a trans-trans to a trans-cis configuration as a result of biphenyl substitution. The packing of the compounds is stabilized by N-H···O and C-H···O hydrogen bonds.
