The title compound, C24H44N2O5, is a 3-amino-5-hydroxy-piperidin-2-one derivative. Single-crystal X-ray diffraction was performed to obtain the relative stereochemistry at the chiral centres. The substituents of the 2-piperidone ring have a trans configuration. The molecule crystallized in a monoclinic cell with a long c axis [47.742 (5) Å]; the space group is P21/c. The crystalline structure is stabilized by hydrogen bonds along the b axis direction.
