The title compound 4 reacted as a dienophile with open-chain and cyclic carbodienes as well as the 1-azadiene 16, to yield different polynuclear isoxazole systems.On the contrary, it gave rise preferentially to a Michael-type reaction with the dimethyluracil derivative 19 affording the cine-substitution product 23, whose structure was determined by an X-ray analysis.Some mechanistic features and synthetic opportunities are emphasized.

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
