Question
Chapter 19, Problem 26P
Interpretation Introduction
Interpretation:
In the given Dieckmann condensation reaction, the structural formula for the possible products is to be written and the major product is to be predicted.
Concept introduction:
The Dieckmann condensation is also known as intermolecular Claisen condensation, which is useful for the synthesis of five or six membered ring cyclic ß-keto esters.
Due to angle strain, the rings smaller than five members are disfavored.
Claisen and Dieckmann condensations are reversible.
