title: An alkynylboronate cycloaddition strategy to functionalised benzyne derivatives.
abstract: A new approach to benzyne precursors has been developed that involves the [4+2] cycloaddition of trimethylsilyl alkynylboronates with 2-pyrones, followed by oxidation and trifluoromethylsulfonylation of the boronate moiety.
