    The title compound, C 21 H 21 N 3 O S, contains an oxazolidinone ring and a sulfonamide group, both characteristic for biologically and pharrmaceutically active compounds. Both stereogenic centres reveal an S absolute configuration. The two oxazolidinone rings are in an envelope conformation with the methylene carbon flap atoms deviating by 0.428 (1) and 0.364 (2) A 7 ˚ from the best least-square planes formed by the four other ring atoms. An intramolecular N—H O hydrogen bond contributes to the folded conformation of the molecule. In the crystal, weak intermolecular C—H O interactions connect the molecules into helices along the the twofold screw axes.
