Abstract: The title compound, C₁₈H₁₂Cl₃NO₃, was synthesized by the intermolecular [3  +  2]-cycloaddition of 2,6-dichlorobenzonitrile oxide and 3-(4-chlorobenzylidene)dihydrofuran-2-one. A spiro junction in the molecule links an isoxazoline ring and a dihydrofuran-2-one ring. Both rings are non-planar, with envelope conformations.
