The Dieckmann condensation is the intramolecular chemical reaction of diesters with base to give β-keto esters. Discovery and development of the reaction are generally credited to Dieckmann, who found that heating an adipic or a pimelic ester with sodium and a trace alcohol led to cyclization with formation of a cyclopentanone or a cyclohexanone. The reaction was first described by Walter Dieckmann in 1894.
