Concept explainers
(a)
Interpretation: For the alkylation of a given compound under two different conditions to form ketoesters A and B, and for each ketoester to form cyclic diketone C and D on treatment with methoxide ion in methanol,
The structure of A and B and indicate the conditions used in the alkylation to form the ketoester has to be given.
Concept introduction: Lithium diisopropylamide is a strong base. Therefore, it can abstract a proton from
Thermodynamic enolate ion is formed at temperature
(b)
Interpretation:
Mechanism for the conversion of keto ester A into cyclic diketone has to be given.
