(a)
Interpretation:
The method of synthesis of given ester has to be stated with the help of crossed Claisen condensation.
Concept introduction:
In crossed claisen condensation, the enolisable ester is deprotonated by alkoxide ion. This enolate ion undergoes a nucleophilic acyl substitution with non-enolisable ester to give a beta-keto ester. It is deprotonated by an alkoxide ion followed by protonation to give beta-keto ester. In this reaction, the electrophilic component is ester without alpha hydrogens.
