Silylacetylenic or olefinic α-iodo ketones were treated with tributyltin hydride and AIBN to give bicyclic ketones by an intramolecular α-carbonyl radicalcyclization reaction. As an application of this radicalcyclization reaction, the total synthesis of (±)-modhephene has been accomplished efficiently.
