Radical ring opening reactions of cyclopropyl ketones mediated by samarium(II) iodide-induced single electron transfer have permitted the elaboration of a tandemrearrangementcyclisation strategy. The resultant samarium enolates may be effectively quenched on oxygen or carbon by electrophiles.

The radical ring-opening reactions of cyclopropyl ketones, mediated by samarium (II) iodide and other electron transfer agents are described. This strategy allows tandemrearrangementcyclisationreactions and the trapping of the resultant samarium (III) enolates by a variety of electrophiles, for the construction of complex bicyclic systems.
