| Research Abstract |
The transition metal-catalyzed insertion reaction of an unsaturated carbon-carbon bond into a carbon-hetero atom bond of an heterocyclic compound is a useful transformation to prepare a more complicated heterocyclic compounds in a single step. However, there is no precedent for such a potentially valuable methodology. We postulated that oxidative addition of cyclic carbonyl compounds to nickel(0) and subsequent decarbonylation are facile and might allow insertion of alkynes. Thus, we developed the decarbonylative addition of anhydrides to alkynes using nickel(0) catalyst to form hetero cyclic compounds, which displays a wide range of biological activities.
