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.
