摘要：

Asymmetric synthesis of a chiral cyclopentadiene (98% ee) was realized for the first time by palladium-catalyzed asymmetric allylation of sodium cyclopentadienide in dioxane. The cyclopentadiene was readily converted into chiral metallocenes of iron, zirconium, and titanium, whose enantiomeric excesses are over 99%. (C) 2003 Elsevier Science Ltd. All rights reserved.
