(4S)-4-Benzyl-N-{(4S)-4-benzyl-2-oxo-13-oxazolidin-3-ylsulfon­yl}-2-oxo-13-oxazolidine-3-carboxamide

摘要

The title compound, C21H21N3O7S, 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) Å 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.
