rac-Ethyl 2-amino-3-hydroxy-3-[4-(methylsulfonyl)phenyl]propanoate

Abstract

In the title compound, C12H17NO5S, the orientations of the 2-ethyl-2-amino-3-hydroxypropanoate group and the 4-methylsulfonyl moiety towards the aromatic ring are periplanar and (−)-anticlinal, respectively. In the crystal packing, the dominant interaction is O—H...N hydrogen bonding, which generates a chain running along [100]. N—H...O and C—H...O interactions are also observed.
