Dimethyl 2-[23-oxo-22,24-diphenyl-8,11,14-trioxa-25-aza-tetra-cyclo-[19.3.1.0(2,7).0(15,20)]penta-cosa-2,4,6,15(20),16,18-hexaen-25-yl]but-2-enedioate.


ABSTRACT: 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.
