X=Y-ZH systems as potential 1,3-dipoles. Part 50:1 phenylselenyl halide induced formation of cyclic nitrones from alkenyl oximes

Oximes possessing γ- δ or ω-alkenyl substituents are cyclised by phenylselenyl bromide, or by phenylselenyl chloride and an appropriate silver salt to the corresponding cyclic nitrones; the seleno nitrones undergo facially specific cycloaddition reactions with N-methylmaleimide; bis(alk-γ,δ-enyl) ketones undergo regiospecific cyclisation and stereospecific intramolecular cycloaddition to furnish spirocyclic products.
