Dimethylcis-4-hydroxymethylpiperidine-2,6-dicarboxylate

The heterocyclic core of the title compound, C10H17NO5, adopts a chair conformation with its three C substituents positioned equatorially. In the crystal, intermolecular O— H N hydrogen bonds between neighbouring molecules lead to chains along b. These chains are connected by hydrophobic interactions, forming infinite layers and N—H O C contacts between molecules of adjacent layers give rise to a three-dimensional structure.
