In the title compound, C13H13ClO4, the dihedral angle between the chloro-benezene ring and the least-squares plane through the 4-meth-oxy-2-oxobut-3-enoate ethyl ester residue (r.m.s. deviation = 0.0975 Å) is 54.10 (5)°. In the crystal, mol-ecules are connected by meth-oxy-ketone and benzene-carboxyl-ate carbonyl C-H⋯O inter-actions, generating a supra-molecular layer in the ac plane.

The asymmetric unit of the title compound, C(18)H(30)N(2)O(4), contains two independent mol-ecules. In each mol-ecule, the cyclo-hexane ring adopts a chair conformation with equatorial orientation of the substituents, and the conformation is stabilized by two intra-molecular N-H⋯O hydrogen bonds, forming rings of S(6) graph-set motif. One eth-oxy group and one ethyl group are disordered over tw...

In the title compound, C(12)H(12)O(4), the dihedral angle between the plane through the phenyl ring and the mean plane of the side chain is approximately 14°. The mol-ecules, which contain an intra-molecular O-H⋯O hydrogen bond, are linked end-to-end by weak C-H⋯O inter-molecular hydrogen-bonding contacts, forming infinite one-dimensional chain systems in the crystal structure.
