A novel route to cyclic imines based on 5-exo radicalcyclization is explored. The radical precursors are imines prepared from allylamine and readily available α-phenylselenenyl ketones.

Phenyl selenium trichloride was used for the introduction of a PhSeCl2-group into the α-position of ketones. These products were converted to enones (hydrolysis/selenoxide elimination) or α-phenylselenoketones (thiourea-reduction).
