The new bicyclic systems with a spiran junction between the two nuclei, 2-isoxazoline and γ-lactone, are obtained by condensation of α-benzylidenyl-γ-butyrolactone and phenylnitroloxide using the microwave oven technique in a dry environment (SiO2). The structures of these new products are identified using 1H, 13C NMR and IR spectroscopic analyzes as well as by a radiocrystallographic study by X-ray diffraction on the single crystal of product 3a.
