The synthesis of highly substituted indenes has been achieved by three different transition metal-mediated methods. The first method involves the palladium-catalyzed carboannulation of internalalkynes. The second method utilizes a two-step approach, which involves first the palladium/copper-catalyzed cross-coupling of terminalalkynes with appropriately functionalized aryl halides, followed by copper-catalyzed
