Triple A: A general asymmetric allylicalkylation of ester enolate equivalents at the carboxylicacid 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 carboxylicacid derivatives without loss of enantiopurity.
