title: Ruthenium(II)-catalyzed cycloaddition of 1,6-diynes with isocyanates leading to bicyclic pyridones.
abstract: [reaction: see text] A ruthenium(II) complex possessing a planar Cp ligand, CpRu(cod)Cl, effectively catalyzed the [2 + 2 + 2] cycloaddition of 1,6-diynes with isocyanates to afford bicyclic pyridones in 58-87% yields.
