(2-tert-Butyl-3-phenyl-2,3-di­hydro­isoxazole-4,5-di­yl)bis­(phenyl­methanone)

The phenyl and tert-butyl groups of the title compound, C₂₇H₂₅NO₃, exhibit a trans configuration in agreement with the stereochemistry of the Z phenyl-N-tert-butyl­nitrone starting material. The attached carbonyl groups are not coplanar with the neighboring di­hydro­isoxazole ring and the phenyl rings they are bonded to, with torsion angles of 59.26 (8), 17.53 (11), 16.52 (12) and 52.86 (7)°. The dihedral angle between the di­hydro­isoxazole ring and the directly attached phenyl group is 86.86 (8)°. There are two nonclassical inter­molecular C—H...O hydrogen-bonding inter­actions that operate together with an inter­molecular C—H...π inter­action to form a supramolecular architecture in the crystal system.
