Abstract
Molecules of the interesting racemic 3,3-diphenylalanine derivative, C 18H19NO4, contain a DTP amino acid residue which adopts a semi-extende d conformation. The values of phi and psi, are -91.0(5) and 130.4(4)de grees, respectively, for the L enantiomer. The crystal structure consi sts of cyclic (urethane)N-H ... O=C(methyl ester) hydrogen-bonded dime rs piled up in columns running parallel to the crystallographic a axis .
