Chiral cyclopentadienyl RhIII complexes efficientlycatalyze enantioselective cyclopropanations of electron-deficient olefins with N-enoxysuccinimides as the C1 unit. Excellent asymmetric inductions and high diastereoselectivities can be obtained for a wide range of substrate combinations. The reaction proceeds undermildconditions without precautions to exclude air and water. Moreover, the synthetic
