In the title compound, C(14)H(13)N(3)O(2), the relative stereochemistry of the three stereogenic C atoms has been determined. In the crystal, N-H⋯O hydrogen bonds link the mol-ecules into chains of inversion dimers running along the b axis.
4R/S-Aminoprolines when present in the X-position of collagen peptide [pro(X)-pro(Y)-Gly]n exhibit pH- and stereochemistry-dependent effects on triplex stability.

Two very rapid yttrium initiators for lactide polymerisation are reported; the nuclearity (monomer vs. dimer) of the initiator controls the stereochemistry of the polylactide produced.
