Abstract: The title compound, C₃₄H₂₄Cl₄N₂O₃, was synthesized by the intermolecular [3+2]-cycloaddition of 2,6-dichlorobenzonitrile oxide and 2,6-bis(benzylidene)cyclohexanone. Three of the rings are linked by two spiro-C atoms. The cyclohexane ring has a chair conformation and the two five-membered isoxazoline rings are envelopes. The crystal packing of the title compound is stabilized by weak C-HO and C-H interactions.
