The synthesis of 2 − methyl − 3 − oxocyclopentanecarboxylic acid is to be outlined and the structure of each intermediate is to be given. Concept Introduction: The addition which takes place between nucleophile and α,β − unsaturated carbonyl compound is known as Michael addition. The α,β − unsaturated compounds represent the Michael acceptor and nucleophile represents the Michael donor. The intramolecular chemical reaction which takes place between diesters and an alkoxide base in order to form β-keto esters is known as Dieckmann condensation.
