S-Phenethyl (2R,3R)-3-{[(R)-tert-butylsulfinyl]amino}-2-fluoro-3-phenylpropanethioate

Abstract

The title compound, C21H26FNO2S2, contains two chiral carbon centres and the absolute configuration has been confirmed as (2R,3R). The dihedral angle between the phenyl rings is 87.1 (2) and the O—C—C—F and F—C—C—N torsion angles are −175.4 (4) and 62.7 (4)°, respectively. In the crystal, N—H...O hydrogen bonds link the molecules into C(4) [010] chains and weak C—H...O and C—H...F interactions cross-link the chains, generating a three-dimensional network.
