title: Nickel-catalyzed regio- and diastereoselective intermolecular three-component coupling of oxabicyclic alkenes with alkynes and organoboronic acids.
abstract: Reaction of oxabicyclic alkenes with alkynes and organoboronic acids in the presence of Ni(cod)(2), P(t-Bu)(3), and CsF in a binary solvent toluene-methanol (1 : 3) at 75 to 85 °C provided exo-5,6-disubstituted 7-oxanorbornene derivatives in good to excellent yields.
