Iridium-catalyzed regioselective decarboxylative allylation of β-ketoacids: efficient construction of γ,δ-unsaturated ketones†
Abstract
A highly regioselective protocol for the direct synthesis of γ,δ-unsaturated ketones from β-ketoacids and allylic alcohols was proposed and accomplished relying on the combination of [Ir(cod)Cl]2 and 10-camphorsulfonic acid via decarboxylative allylation.
