Article abstract of DOI:10.1016/0040-4039(91)80051-7

4,5-Dihydro-4,5-dimethylene-3-phenyl-isoxazole (the isoxazole analogue of ortho-quinodimethane) has been generated in situ from 4,5-bis(bromomethyl)-3-phenyl-isoxazole by sodium iodide induced 1,4-elimination process and trapped with symmetrical and unsymmetrical dienophiles.
