Dieckmann condensation Intramolecular claisen condensation can be carried out with diesters, just as intramolecular aldol condensations can be carried out with diketones Called the Dieckmann condensation the reaction works best on 1, 6-diesters and 1,7 e diesters, and the products of such reactions are five-and six- membered 画ccc阝- keto estersOrganic Chemistry Organic Chemistry Xiamen Xiamen University University Dieckmann Condensation „ Intramolecular Claisen condensation can be carried out with diesters, just as intramolecular aldol condensations can be carried out with diketones. Called the Dieckmann condensation, the reaction works best on 1,6-diesters and 1,7- diesters, and the products of such reactions are five￾and six-membered cyclic β-keto esters
