Dicobalt octacarbonyl catalyzed carbonylated cycloaddition of triynes to functionalized tetracycles.
[reaction: see text]. We have demonstrated that a dicobalt octacarbonyl catalyzed double [2 + 2 + 1] carbonylative cycloaddition reaction of triyne can be carried out to yield a novel 5.5.5.6 tetracyclic di-enone system.
