(a)
Interpretation:
The validation of the fact that the given keto ester is formed by Dieckmann condensation has to be predicted and the structure of starting diester if applicable has to be drawn.
Concept introduction:
An internal condensation reaction of a diester forms a ring compound. Such an internal claisen cyclization is known as a Dieckmann condensation reaction or more commonly it is known as a Dieckmann cyclization. This reaction is useful in the formation of five and six membered rings. Rings which are smaller than five carbon atoms or larger than six carbon atoms are rarely formed by this reaction.
(b)
Interpretation:
The validation of the fact that the given keto ester is formed by Dieckmann condensation is to be predicted and the structure of starting diester if applicable is to be drawn.
