New Features of Isoxazole Chemistry. The Reaction of Ethyl 4-Nitro-3-phenylisoxazole-5-carboxylate with 2,3-Dimethylbuta-1,3-diene

The title compound (2) was found to undergo a (2 + 4) cycloaddition with 2,3-dimethylbuta-1,3-diene affording the tetrahydro-1,2-benzisoxazole (3), which could be easily converted into the corresponding dihydro derivative (4) by elimination of the NO2 and
