The cobalt-catalyzed Diels-Alder reaction of alkynyl pinacol boronic esters with various dienes generates cycloadducts in very good regioselectivity. A reaction sequence (Diels-Alder reaction, Suzuki coupling, DDQ oxidation) was successfully performed as a one pot operation without isolation of the intermediates.

Aryne Diels-Alder reactions with functionalized acyclic dienes give useful cis-substituted dihydronaphthalene building blocks in good yield. Asymmetric aryne cycloadditions with Oppolzer's sultam as a chiral auxiliary are also reported .
