Abstract
New C2-symmetric chiral di-2-pyridyl ketones were prepared from readily available chiral bromopyridines. Their complexes with copper were synthesized and characterized by X-ray crystallography. The copper complexes were prepared in situ with the triflate anion and were found to be active in the catalysis of cyclopropanation with diazo esters and alkenes. Reaction yields were excellent and enantioselectivities of up to 61% were observed.
