An efficient catalytic protocol for the synthesis of δ,δ-bis(aryl)-substituted β-keto esters has been developed. This method involves the Lewis acid catalysed disubstitution reaction of ester-substituted silyl enol ether acetals with a series of aromatic nucleophiles to afford valuable functionalized β-keto esters with several sites available for further derivatisation.
