Abstract: The title compound, C40H41NO8, is a product of the reduction of the cyclic carbonyl group of the [gamma]-piperidone subunit of the aza-14-crown-4 ether with subsequent re-esterification of its dimethyl butenoate substituent into a monoethyl monomethyl group. The aza­crown macrocycle exhibits a bowl conformation with a dihedral angle of 70.82 (5)° between the benzene rings fused to it. The piperidine ring adopts a chair conformation and the methyl ethyl ethyl­enedi­carboxyl­ate fragment has a cis conformation, with a dihedral angle of 66.51 (7)° between the two carboxyl­ate groups. The ethyl group is disordered over two sites with occupancies of 0.70 (1):0.30 (1). In the crystal, mol­ecules form inversion dimers, via pairs of O-H...O hydrogen bonds, that stack along the a axis.
