(a) Interpretation: Steps to synthesize the given compound using either an aldol addition or aldol condensation are to be proposed. Concept introduction: The product of an aldol addition is a β- hydroxycarbonyl compound while the product of an aldol condensation is an α,β- unsaturated carbonyl compound. The new C − C bond that is formed in an aldol reaction (addition or condensation) appears between the α and β carbons in the product, so a transform that undoes an aldol reaction involves disconnecting that bond. In constructing the precursors to an aldol reaction, the β- carbon in the aldol product is the carbonyl carbon.
