摘要

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 spiro-cycloalkane fragments. One of ...
