The title compound, C24H28N2O7, is the product of a novel synthetic procedure in which a highly functionalized heterocycle is formed. The crystal packing involves dimers, utilizing non-classical weak C-H⋯O interactions (ca 3.36-3.46 Å) and an antiparallel π-π interaction between two of the pseudo-aromatic isoxazole moieties. These dimers are associated into a three-dimensional network via further nonclassical hydrogen bonding.
