Abstract: The title compound, C₃₃H₂₂Cl₄N₂O₃, was synthesized by the intermolecular [3+2]-cycloaddition of 2,6-dichlorobenzonitrile oxide and 2,5-bis(benzylidene)cyclopentanone. Three five-membered rings are linked by two spiro-C atoms. The cyclopentane ring has a twist conformation and the two isoxazoline rings are envelopes. The crystal packing of the title compound is stabilized by weak C-HCl and C-H interactions.
