Enantioselective Synthesis of [7]Helicene: Dramatic Effects of Olefin Additives and Aromatic Solvents in Asymmetric Olefin Metathesis

The asymmetric synthesis of [7]helicene was accomplished in good ee (80 %) by kinetic resolution by means of asymmetric olefin metathesis. Three key factors contributed to the success of the kinetic resolution: the use of new Ru‐based olefin metathesis catalysts bearing C1‐symmetric N‐heterocyclic c...
