Abstract
AbstractA set of 16 chiral ruthenium complexes containing atropisomerically stable N‐Heterocyclic Carbene (NHC) ligands was synthesized from prochiral NHC precursors. After a rapid screening in asymmetric ring‐opening‐cross metathesis (AROCM), the most effective chiral atropBIAN‐NHC Ru‐catalyst (up to 97 : 3 er) was then converted to a Z‐selective catechodithiolate complex. The latter proved to be highly efficient in Z‐selective AROCM of exo‐norbornenes affording valuable trans‐cyclopentanes with excellent Z‐selectivity (>98 %) and high enantioselectivity (up to 96.5 : 3.5 er).
