چکیده
The title compound, C(17)H(17)NO(5), crystallizes with two mol-ecules (A and B) in the asymmetric unit. The conformational structures of the two mol-ecules show small but significant differences in the dihedral angles between the two aryl rings with values of 18.8 (1)° for mol-ecule A and 7.5 (1)° for mol-ecule B. In mol-ecule A, the propano-ate group is twisted out of the plane of the benzene group [C(ar)-C(ar)-C-C torsion angle = -44.9 (2)°], while for mol-ecule B, this group lies closer to the plane [C(ar)-C(ar)-C-C torsion angle = 8.6 (3)°]. C-H⋯O inter-actions characterize the crystal-packing inter-actions in this compound.

In the title compound, C(12)H(17)NO(5)S, the orientations of the 2-ethyl-2-amino-3-hy-droxy-propano-ate group and the 4-methyl-sulfonyl moiety towards the aromatic ring are periplanar and (-)-anti-clinal, respectively. In the crystal packing, the dominant inter-action is O-H⋯N hydrogen bonding, which generates a chain running along [100]. N-H⋯O and C-H⋯O interactions are also observed.

The complete mol-ecule of the title compound, C(42)H(36)N(6)O(2), is generated by a crystallographic twofold axis with two C atoms of the central phenyl group lying on the axis. In the independent part of the mol-ecule, one amino group is involved in an intra-molecular N-H⋯O hydrogen bond, and the two adjacent phenyl rings are twisted from the plane of the pyrazolone ring with dihedral angles o...
