approach for the conjugate arylation reaction of unsaturated Meldrum’s acid derivatives is reported. The reaction takes place through a Boron-Zinc exchange reaction between arylboronic acids and diethylzinc and the subsequent transfer of thus generated reactive aryl groups to the β-position of the double bond of the Meldrum’s derivatives. The compounds obtained are valuable synthetic intermediates and
