Irradiation of ketoxime O-(S-methyl xanthates) containing a γ,δ-double bond leads to a dihydropyrrole through cyclisation of an intermediate iminyl radical in a radical chain reaction. The last propagation step involves transfer of a dithiocarbonate group and various external radical traps can be incorporated into the medium, allowing access to a variety of substituted dihydropyrroles.
