Palladium‐Catalyzed Allylic Alkylation of Carboxylic Acid Derivatives: <i>N</i>‐Acyloxazolinones as Ester Enolate Equivalents

Abstract

Triple A: A general asymmetric allylic alkylation of ester enolate equivalents at the carboxylic acid oxidation state is reported. N-Acylbenzoxazolinone-derived enol carbonates were synthesized and employed in the palladium-catalyzed alkylation reaction. The imide products were readily converted into a series of carboxylic acid derivatives without loss of enantiopurity.
