(a)
Interpretation: The given compounds has to be prepared from methyl phenyl
Concept introduction: A crossed-claisen condensation is also a condensation reaction between a ketone and an ester. Primarily one product will form from crossed-claisen condensation when one of the ketone or easter do not have any alpha hydrogens.
If both ester and ketone have alpha hydrogens then primarily one product can form if LDA is used to remove alpha hydrogen to form the enolate ion. The other compound is added slowly to the enolate ion.
