Chapter 24, Problem 24.18P
Interpretation Introduction

Interpretation: The two different crossed Claisen reactions that form avobenzone are to be shown.

Concept Introduction: In crossed claisen condensation reaction, the base abstracts the acidic proton from α− carbon atom of an ester to form enolate. This enolate reacts with carbonyl compound of other ester that leads to the formation of a β-keto ester. The crossed Claisen condensation always takes place between the two different carbonyl compounds.
