Dieckmann Cyclization

Dieckmann Cyclization Definition:

The Dieckmann cyclization is an intramolecular reaction that results in a beta keto ester as the end product.

Dieckmann Cyclization Explained:

The Dieckmann is an intramolecular condensation, a molecule that has two esters. A dicarboxylic ester is cyclized to a beta-ketonic ester through the action of a base. The dicarboxylic ester must have at least one alpha-hydrogen atom and the carbalkoxy groups must be situated that cyclization will result in rings around the molecule.
