Photochemical transformation of γ,δ-unsaturated ketone O-(p-cyanophenyl)oximes to 3,4-dihydro-2H-pyrrole derivatives

Abstract

γ,δ-Unsaturated ketone O-(p-cyanophenyl)oximes are transformed into 3,4-dihydro-2H-pyrroles by a photochemical reaction in the presence of 1,5-dimethoxynaphthalene. The present transformation proceeds via photosensitized electron transfer between 1,5-dimethoxynaphthalene and O-(p-cyanophenyl)oximes.
