(2S,3R,4R,5R)-3,4-Dihydroxy-5-(hydroxymethyl)pyrrolidine-2-carboxylic acid [(2S,3R,4R,5R)-3,4-dihydroxy-5-(hydroxymethyl)proline]

Abstract

The crystal structure of the title compound, C6H11NO5, establishes the relative configuration at the four stereogenic centres; the absolute configuration is determined by the use of d-glucuronolactone as the starting material for the synthesis. Molecules are linked by intermolecular O—H...O and N—H...O hydrogen bonds into a three-dimensional network, with each molecule acting as a donor and acceptor for five hydrogen bonds.
