چکیده
The mol-ecule of the title compound, C(16)H(23)N(3)O(5), is twisted about the chiral C atom, the dihedral angle formed between the amide residues being 79.6 (3)°. The conformation about the imine bond [1.278 (5) Å] is E. In the crystal, O-H⋯O and N-H⋯O hydrogen bonding between the hy-droxy, amine and carbonyl groups leads to the formation of supra-molecular layers, which stack along the c-axis direction.

The mol-ecule of the title compound, C(18)H(19)N(3)O(5), adopts a curved arrangement with the terminal benzene rings lying to the same side. The hydroxyl-benzene ring is close to coplanar with the adjacent hydrazine residue [dihedral angle = 11.14 (12)°], an observation which correlates with the presence of an intra-molecular O-H⋯N hydrogen bond. The benzyl ring forms a dihedral angle of 50.84 ...

The title compound, C18H30N2O5S, was synthesized by the reaction of tert-butyl 2-(iso-butyl-amino)-ethyl-carbamate with p-meth-oxy-phenyl-sulfonyl chloride. In the mol-ecule, two intra-molecular C-H⋯O hydrogen bonds are observed. In the crystal, mol-ecules are linked by N-H⋯O hydrogen bonds involving the imino group N atom and the ester group O atom into chains running parallel to the b axis. T...
