Abstract

4-Methylene-5-morpholino-3-phenyl-4,5-dihydroisoxazole (1) reacts with nitrones (2) to give a mixture of diastereoisomeric cycloadducts, namely spiro[isoxazolidine-5,4′-isoxazolines] (3) and (4). The structure and steric configuration of the spiro derivatives have been assigned on the basis of 1H and 13C NMR evidence and by X-ray analysis.
