Photochemical Radical Cyclization of γ,δ-Unsaturated Ketone Oximes to 3,4-Di— Dihydropyrroles are synthesized from γ,δ-unsaturated oximes
30- 097 hydro-2H-pyrroles.
via two types of photochemical processes. Cyclization of alkyl ketone oximes (I), (V),
(VII) and (X) is induced by photochemical electron transfer from exited DMN. Conjugated ketone oximes (XIII), (XV) and (XVII) are cyclized by energy transfer from photochemical DMN. — (KITAMURA, M.; MORI, Y.; NARASAKA*, K.; Tetrahedron
