A [4+2] cycloaddition/retro-cycloaddition route to functionalised aromatic boronic esters is outlined. A range of electron deficient dienes (2-pyrones) and dienophiles (alkynylboronates) were found to participate in the reaction. Furthermore, high levels of regiocontrol could be obtained in this process and a consistent mode of alkyne insertion has been uncovered.
