Ye, BaihuaCramer, Nicolai2015-09-282015-09-282015-09-28201510.1055/s-0034-1380765https://infoscience.epfl.ch/handle/20.500.14299/119020WOS:000356859200012The demand for efficient chiral cyclopentadienyl ligands (Cp-x) has increased significantly in recent years, partly because Cp*Rh(III) species have been developed as powerful catalysts for directed C-H functionalization reactions. However, a lack of suitable Cp-x ligands has hampered the development of the corresponding enantioselective processes. We report expansions of the libraries of two generations of Cp-x ligands and their corresponding rhodium(I) complexes. The potential of the rhodium complexes as catalysts was evaluated in enantioselective C-H functionalizations involving cyclizations across tethered aldehydes. The mild reaction conditions permit the syntheses of hydroxychromanes and phthalides in good yields and high enantioselectivities.asymmetric catalysisligandsrhodiumcyclizationsheterocyclestext::journal::journal article::research article
