(1R*,21S*,22R*,24S*)-Methyl ethyl 2-[23-hydroxy-22,24-diphenyl-8,11,14-trioxa-25-azatetracyclo[19.3.1.0 2,7.015,20]pentacosa-2,4,6,15(20),16,18-hexaen-25-yl]but- 2-enedioate

The title compound, C40H41NO8, is a product of the reduction of the cyclic carbonyl group of the γ-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.
