Abstract
Homochiral bis(oxazolinyl)pyridine type ligands were synthesized from (S)-valine and converted into their Cu(II) complexes. Reduction of these Cu(II) complexes into Cu(I) with diazoesters was studied by uv-vis and epr spectroscopy. The enantioselective cyclopropanation reaction was carried out using styrene as a model substrate. The Cu(II) complexes of the type 5 were synthesized for cyclopropanation reaction. The reduction of Cu(II) into Cu(I) with diazoesters was studied by uv-vis and epr spectroscopy.
