O-EthylS-{(S)-1-oxo-1-[(R)-2-oxo-4-phenyloxazolidin-3-yl]propan-2-yl} carbonodithioate

Abstract

In the title compound, C15H17NO4S2, synthesized by addition ofO-ethylxanthic acid potassium salt to a diastereomeric mixture of (4R)-3-(2-chloropropanoyl)-4-phenyloxazolidin-2-one, the oxazolidinone ring has a twist conformation on the C—C bond. The phenyl ring is inclined to the mean plane of the oxazolidinone ring by 76.4 (3)°. In the chain the methine H atom is involved in a C—H...S and a C—H...O intramolecular interaction. In the crystal, molecules are linked by C—H...π interactions, forming chains along [001]. TheSconfiguration at the C atom to which the xanthate group is attached was determined by comparison to the knownRconfiguration of the C atom to which the phenyl group is attached.
