A highly active chiral ruthenium-based catalyst for enantioselective olefin metathesis

摘要

A chiral Ru-based olefin metathesis catalyst bearing a chiral NHC ligand that is both C-1-symmetric and monodentate is described. The catalyst shows increased reactivity in comparison to existing chiral Ru-based catalysts that possess a C-2-symmetric NHC and successfully induces asymmetry in desymmetrization reactions.
