    摘要: A method of synthesizing a substituted cyclopentadiene compound. The synthesis comprises a step of cyclizing, in the presence of a phosphorous pentoxide/methanesulfonic acid reagent, an alpha,beta-unsaturated carboxylic acid, cycloalkyl ester compound to make a substituted cyclopentenone compound, and converting the substituted cyclopentenone compound to the substituted cyclopentadiene compound. Also, a method of synthesizing a substituted metallocene compound comprising a metal-(substituted cyclopentadienyl ligand) complex, wherein the substituted cyclopentadienyl ligand is made from the substituted cyclopentadiene compound. A metal-(substituted cyclopentadienyl ligand) complex and substituted metallocene compound made by the method and a substituted metallocene catalyst made therefrom.

    摘要: Se proporcionan nuevos ligandos quirales bidentados enantioméricamente enriquecidos de fórmula (I) o sus correspondientes enantiómeros de fórmula (I') que forman una coordinación tipo puente con complejos de dicobaltohexacarbonilo, en particular de manera diastereoselectiva cuando el alquino es monosustituido o disustituido con los dos sustituyentes diferentes. Se proporciona asimismo un procedimiento para la preparación de dichos ligandos quirales y un procedimiento para la preparación de los complejos de alquino-dicobaltotetracarbonilo. Los nuevos complejos de alquino-dicobaltotetracarbonilo formados permiten llevar a cabo la reacción de Pauson-Khand de manera enantioselectiva y con rendimientos elevados y, por tanto, son útiles en la síntesis de productos ciclopentánicos farmacéuticos y/o con actividad biológica.
