The four-membered cyclic nitrones (2,3-dihydroazete 1-oxides) 1a-d react with dimethyl acetylenedicarboxylate by 1,3-dipolar cycloaddition to give the dihydroazetoisoxazole derivatives 2a-d; cyclic nitrone 1e reacts in a similar way via the not iso

The formation of a thermally unstable (4+2)-cycloadduct, a 4H-1,2-oxazine 2-oxide derivative (1), from the reaction of 1-nitrocyclopentene with 1-phenyl-2-(1-pyrrolidinyl)acetylene has been proven by the structure elucidation of isoxazole derivative 3 whi
