A novel method of annulation was realized from ketones through α,β-epoxy sulfoxides with the aid of endo-type intramolecular radical cyclization. In these reactions 1-chloroalkyl phenyl sulfoxides having phenylseleno group on an end of the alkyl group acted as synthons of the annulation.
Fused and spiro carbocyclic compounds were synthesized by electrochemical reductions of bromoalkylcyclo-hexenones using cobalt or nickel complexes as mediators.
