Abstract

In the reactions of nitrone 1 with several methylene-γ-bulyrolactones 2-5 we have isolated and identified in all the cases the corresponding [3+2] cycloadducts. In all the adducts the oxygen atom of the dipole has linked to the more substituted carbon atom of the exocyclic double bond of the lactone. For lactone 5 the exocyclic double bond has shown higher reactivity than the endocyclic. Herein three new heterocyclic skeletons are reported.
