Three-component one-pot reactions of bromotrinitromethane with bicyclobutylidene and
methylenecyclobutanes provide a simple route to halogen-substituted isoxazolidines
of mixed composition. With these same olefins, iodotrinitromethane gives adducts which
decomposed rapidly to yield the corresponding isoxazolines. Reaction of bromotrinitromethane
and bicyclobutylidene with electron-deficient alkenes produced isoxazolidines together
with bromotrinitroalkanes as side products.
