Descripción
Sumario: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 acetyl­enedicarboxyl­ate. The piperidinone ring exhibits a distorted chair conformation and the dimethyl acetyl­enedicarboxyl­ate fragment has a cis configuration with a dihedral angle of 56.61 (5)° between the two carboxyl­ate groups. The crystal packing is stabilized by the weak C—H⋯O hydrogen bonds.
