Description: WEBThe Dieckmann Cyclization Diesters can undergo an intramolecular reaction, called the Dieckmann condensation, to produce cyclic beta-keto esters. This reaction works best with 1,6-diesters, which produce five-membered rings, and 1,7-diesters which produce six membered rings.

Description: WEBSep 28, 2023 · Intramolecular Claisen cyclization of a 1,6-diester gives a five-membered cyclic β -keto ester, and cyclization of a 1,7-diester gives a six-membered cyclic β -keto ester. The mechanism of the Dieckmann cyclization, shown in Figure 23.6, is the same as that of the Claisen condensation.

Description: WEBThe Dieckman condensation is an acetoacetic ester condensation in which 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 a 4-membered ring or larger ring.

Description: WEBThe Dieckmann condensation is an organic reaction which is used to form a carbon-carbon bond between two tethered ester groups using an alkoxide base in alcohol. The resulting product is a cyclic β-ketoester. This reaction is an intermolecular form of Claisen condensation [1-3]. D i e c k m a n n C o n d e n s a t i o n.
