Intramolecular and intermolecular ketone–ester reductivecouplingreactionspromoted by SmI2 have been studied. Substituted 2-hydroxy-5-ethoxycarbonylcyclopentanones, 5-ethoxycarbonylcyclopentenones and α-ketols were prepared in moderate to good yields at room temperature or under reflux under neutral conditions.
