Claisen Condensation
Dieckmann Condensation

The base-catalyzed intramolecular condensation of a diester. The Dieckmann Condensation works well to produce 5- or 6-membered cyclic ß-keto esters, and is usually effected with sodium alkoxide in alcoholic solvent.
The yields are good if the product has an enolizable proton; otherwise, the reverse reaction (cleavage with ring scission) can compete. See the Claisen Condensation.
Mechanism
The mechanism is similar to the Claisen Condensation.
