Synthesis of Citral: Rearrangements and Applications

This lecture covers the industrial application of the synthesis of citral, including enol ether formation, Claisen rearrangement, and the Wagner-Meerwein rearrangement. It explores the key role of citral A in the synthesis of Vitamin A and the rearrangements involving hydride and alkyl shifts. Additionally, it discusses the Baeyer-Villiger oxidation, Pinacol rearrangement, Beckmann rearrangement, and the rearrangement of nitrenoids. The lecture also delves into the generation of ketenes through the Wolff rearrangement, highlighting their electrophilic nature and in situ trapping by nucleophiles.
