Article abstract of DOI:10.1016/S0040-4039(00)97218-6

A series of unsaturated α-diazo carbonyl compounds underwent enantioselective intramolecular cyclopropanation (ee = 4-77percent) when treated with an enantiomerically pure chiral copper catalyst.The nature of the diazo substrate was critical: α-diazo ketones gave the best enantioselectivities whereas α-diazo β-keto ester systems showed diminished enantioselectivities.
