A series of new 3-(4-oxo-4H-chromen-3-yl)-3a,6a-dihydropyrrolo [3,4-d]isoxazole-4,6-dione have been synthesized by the reaction of N-arylmaleimides with nitrile oxide, prepared from α-chloro-4-oxo-4Hchromen-carbaldehyde oximes in situ through 1,3-dipolar cycloaddition reaction. The structures of all
