ChemInform Abstract: An Alkynylboronate Cycloaddition Strategy to Functionalized Benzyne Derivatives

The cycloaddition of 2‐pyrones with alkynylboronate (II) followed by C‐B bond oxidation and a subsequent triflation gives rise to mixtures of regioisomers (VI) and (VII), which are shown to be useful benzyne precursors.
