Özet

Grimes possessing gamma- and delta -alkenyl substituents are cyclised by N-bromo- or N-iodosuccinimide, iodine or IC1 to the corresponding cyclic nitrones or their dimeric H-bonded hydroiodide salts in good yield; facially specific cycloaddition of these nitrones, and others derived by cyclisation of delta,delta -bis(alkenyl) ketoximes or by iodine induced addition of acetaldoxime to cyclohexene, furnish isoxazolidines.
