Article abstract of DOI:10.1016/S0040-4020(98)00499-2

Copper(I) complexes derived from semicorrins, azasemicorrins and bisoxazolines are efficient catalysts for the enantioselective cyclopropanation of silyl enol ethers with diazoacetates. The resulting cyclopropanes can be converted to γ-ketocarboxylates by
