Dieckmann condensationThe Dieckmann condensation[1][2][3] is the intramolecular chemical reaction of diesters with base to give β-ketoesters.[4][5]. It is named after the German chemist Walter Dieckmann (1869–1925). The equivalent intermolecular reaction is the Claisen condensation. Reaction MechanismProduct highlightThe acidic hydrogen between the two carbonyl groups is deprotonated in step four. Protonation with a Brønsted-Lowry acid (H3O+ for example) re-forms the β-keto ester. [6] This deprotonation step is the driving force for this reaction. References
