Seven optically active 3-oxabicyclo-[3.1.0]-hex-2-one derivatives (or bicyclic lactones) were prepared from unsaturated esters of diazoacetic acid by the asymmetric intramolecular carbon addition under the action of a chiral copper catalyst, (S)-7644. The merit of this method is its simple operation using commercially available reagents. The structure of the products obtained were confirmed by elemental analysis, IR, NMR and the specific rotation, the e. e. values were also determined.
