Tetrahydroindenes including spiro-cyclopentyl and -cyclohexyl fragments were successfully synthesized either via base-catalyzed cyclization of the respective γ-diketone or via acid-catalyzed Nazarov cyclization of the corresponding divinylketones. These substituted cyclopentadienes were metallated with nBuLi. The following reaction of the lithium salts with Cp*ZrCl3 gave three novel zirconocenes bearing
