Asymmetric Allylic Alkylation of Cyclic Vinylogous Esters and Thioesters by Pd‐Catalyzed Decarboxylation of Enol Carbonate and β‐Ketoester Substrates

Abstract

Excellent yields and enantioselectivities were achieved for the palladium-catalyzed asymmetric allylic alkylation of vinylogous thioesters. The close-to-neutral reaction conditions ensure that this reaction can tolerate a wide range of functionalities. Furthermore, this approach provides a convenient protocol for the synthesis of synthetically important α,α- and γ,γ-disubstituted cycloalkenones.
