Enantioselective synthesesO 0031 Chiral Tetrafluorobenzobarrelenes as Highly Efficient Ligands for the Rhodium-
-Catalyzed Asymmetric 1,4-Addition of Arylboronic Acids. — New C2-symmetric chiral diene ligands bearing a tetrafluorobenzobarrelene framework and (-)-menthyl groups as chiral auxiliaries are used to give β-arylcarbonyl compounds (III) and (V) in high yields with high enantioselectivity. — (NISHIMURA*, T.; NAGAOSA, M.; HAYASHI, T.; Chem.
