(S)-Benzyl 2-amino-3-(4-hydroxyphenyl)propanoate
The title compound, C(16)H(17)NO(3), adopts a folded conformation in the crystal structure. The crystal packing is stabilized by inter-molecular O-H⋯O and N-H⋯O hydrogen-bonding inter-actions. The absolute configuration was assigned assuming that the absolute configuration of the starting material l-tyrosine was retained during the synthesis.

The title compound, C(35)H(31)NO(3), was obtained by the reaction of (S)-benzyl 2-amino-3-(4-hy-droxy-phen-yl)propano-ate and (chloro-methane-tri-yl)tribenzene. The enanti-omer has been assigned by reference to an unchanging chiral centre in the synthetic procedure. In the crystal, mol-ecules are linked into chains running along the a axis by inter-molecular O-H⋯O hydrogen bonds.

The title compound, C(14)H(17)NO(2)S(2), was synthesized by asymmetric aldol condensation of N-acyl-thia-zolidinethione with acetaldehyde. In the mol-ecule, the thia-zolidine five-membered ring assumes an envelope conformation. Inter-molecular C-H⋯O and intra-molecular O-H⋯O and C-H⋯S hydrogen bonding helps to stabilize the structure.

There are two independent mol-ecules in the asymmetric unit of the title compound, C(26)H(26)N(4)OS. In each mol-ecule, the thienopyrimidine fused-ring system is essentially planar with a maximum deviation of 0.0409 (18) for the N atom. In one mol-ecule, this ring system forms diherdral angles of 84.8 (1) and 67.6 (1)° with the adjacent phenyl and benzyl rings, respectively, while the correspon...

The title compound, C(21)H(21)N(3)O(7)S, 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 methyl-ene carbon flap atoms deviating by 0.428 (1) and 0.364 (2) Å from the best least-squar...
