چکیده

The title compound, C(39)H(37)NO(8), is a product of the Michael addition of the cyclic secondary amine subunit of aza-14-crown-4 ether to dimethyl acetyl-enedicarboxyl-ate. The piperidinone ring exhibits a distorted chair conformation and the dimethyl acetyl-enedicarboxyl-ate fragment has a cis configuration with a dihedral angle of 56.61 (5)° between the two carboxyl-ate groups. The crystal packing is stabilized by the weak C-H⋯O hydrogen bonds.

The title compound crystallizes as a chloro-form solvate, C(20)H(23)N(3)O(3)S·CHCl(3), with two crystallographically independent units. The independent units have distinctly different inter-action patterns between the aza-crown macrocycle and the chloro-form solvent mol-ecule. In one of them, the chloro-form mol-ecule forms C-H⋯N and Cl⋯H-C hydrogen bonds with the aza-crown macrocycle (as a pro...
