(a)
Interpretation:
To identify the appropriate base-solvent pair to accomplish a Claisen condensation with the ester.
Concept introduction:
For a Claisen condensation reaction, unwanted transesterification and saponification reactions can be avoided if the base that is added is the same as the alkoxide leaving group on the ester and if the alcohol solvent is the conjugate acid of that base.
(b)
Interpretation:
To identify the appropriate base-solvent pair to accomplish a Claisen condensation with the ester.
Concept introduction:
For a Claisen condensation reaction, unwanted transesterification and saponification reactions can be avoided if the base that is added is the same as the alkoxide leaving group on the ester and if the alcohol solvent is the conjugate acid of that base.
