7-Isopropylidene-N²,N³,N⁵,N⁶-tetramethoxy-N²,N³,N⁵,N⁶-tetramethylbicyclo[2.2.1]hepta-2,5-diene-2,3,5,6-tetracarboxamide

Abstract

Although the mol­ecular structure of the title compound, C22H32N4O8, displays a twofold symmetry of the mol­ecule including the meth­oxy and methyl substituents, no crystallographic twofold symmetry is observed in the X-ray structure analysis. The carbonyl O atoms alternately point to different sides of the plane defined by the carbonyl C atoms. Two meth­oxy groups are oriented inside the mol­ecules cavity. The H atoms of two methyl groups are disordered over two orientations and were refined using a split model.
