A CpRu-based bifunctional catalyst system (Cp = η(5)-C(5)(CH(3))(5)) with a suitably-designed PN ligand (PN = chelating tertiary phosphine-protic amine ligand) has been developed for a regioselective lactonization of unsymmetrically substituted 1,4-diols, which may provide an expeditious access to a variety of lactone lignans.
一种基于 CpRu 的双功能催化剂体系（Cp = η(5)-C(5)(CH(3))(5)），与一种经过适当设计的 PN 配体（PN = 螯合型三级膦-质子胺配体）相结合，已被开发用于非对称取代的 1,4-二醇的区域选择性内酯化反应，这可能为各种内酯木脂素提供一种快速的合成途径。
