✦ Synopsis

The title compound, C 6 H 8 N 2 O 3 S 2 ÁH 2 O, was synthesized from l-erythrulose and the structure of the enantiopure (4R,9S) diastereoisomer has been determined. The structure is a hydrate and the water molecules establish a hydrogen-bond network that involves the hydroxymethyl group as well as one N and one S atom.
