Notes:
The title compound, C33H26N2O4, is derived from an unexpected spiran synthesis. Its crystal structure has been determined at room temperature. The skeleton is composed of a spiro[4.4] system formed by an isoxazolone and a substituted pyrroline ring obtained by a series of tandem reactions. The carbonyl exocyclic bond angles [121.9 (2) and 129.9 (2)°] of the isoxazolone ring show the usual asymmetry.
