Question

Question: What two β-keto esters are formed in the Dieckmann reaction of the following diester?

Short answer

Answer

Step-by-step solution

Dieckmann reaction

It involves the formation of beta-keto esters by diesters in the presence of a base. It is referred to as an intramolecular reaction.

Formation of products

The dieckmann reaction of diethyl 3,3-dimethylhexanedioate results in the formation of ethyl 2,2-dimethyl-5-oxocyclopentanecarboxylate and ethyl 4,4-dimethyl-2-oxocyclopentanecarboxylate.

The reaction is shown below:
