✦ Synopsis
The absolute configuration has been determined for the title compound, C 14 H 18 N 2 O 6 S, a fluorescent dipeptide analogue, which can act as a rigid backbone chromophore in peptides. Intermolecular N-HÁ Á ÁO C hydrogen bonds [HÁ Á ÁO = 2.37 (2) A ˚] are observed in the crystal packing.
