文摘

Organocatalytic desymmetrization of meso-forms of organometallic anhydrides is unknown. Scope of organocatalysts, including Fu, Rawal and different squaramides. Solvent and reaction conditions optimization up to 98% enantiomeric excess. First example of organocatalytic desymmetrization of ferrocene anhydride.
