Preformed lithiumenolates of ketones react with acyclic α,β-unsaturated ketones to give 1,5-diketones in good chemical yields. A strong correlation exists between enolate geometry and product stereochemistry; enolates having the configuration provide anti addition products while enolates usually provide the syn diastereomers.
