Concept explainers
(a)
Interpretation:
The compounds required for the condensation to synthesise the given compound are to be stated.
Concept introduction:
In base-catalysed aldol condensation, nucleophilic addition of an enolate ion takes place on a carbonyl group. In first step, an alpha proton is removed to produce enolate ion. It adds to the carbonyl group. In the next step, protonation of alkoxide gives the aldol product.
(b)
Interpretation:
The compounds required for the condensation to synthesise the given compound are to be stated.
Concept introduction:
Michael addition is a conjugate addition or 1,4-addition of a resonance stablised carbanion to a conjugated double bond. The conjugate double bond of
(c)
Interpretation:
