Facile preparations of chiral [Ru(Cp*)]- and [Ru(Cp')]-based allyl complexes featuring N,O chelate derived from (+)-nopinone are described. Single crystal X-ray structural analysis of one complex revealed the preferential configuration of the ruthenium centre and the orientation of the unsymmetrical allylic substituent. Applications of these complexes in catalysis for nucleophilic allylic substitution allowed regio- and enantioselective formation of branched allyl ethers from phenols.
描述了一种通过（+）-诺蒎酮衍生的 N,O 螯合配体，来制备手性[Ru(Cp*)]-和[Ru(Cp')]-烯丙基配合物的简便方法。一个配合物的单晶 X 射线结构分析表明了钌中心的优先构型和不对称烯丙基取代基的取向。这些配合物在亲核烯丙基取代反应中的应用，可以从酚类化合物中区域和对映选择性地形成支链烯丙基醚。
