Highly enantioselective copper-catalyzed electrophilic trifluoromethylation of β-ketoesters
Enantioselective Cu-catalyzed trifluoromethylation of β-ketoesters using commercially available trifluoromethylating reagents is reported. A number of αCF3 β-ketoesters are obtained with up to 99% ee. The trifluoromethylated products were then transformed diastereoselectively to α-CF3 β-hydroxyesters w...

| Summary: | Enantioselective Cu-catalyzed trifluoromethylation of β-ketoesters using commercially available trifluoromethylating reagents is reported. A number of αCF3 β-ketoesters are obtained with up to 99% ee. The trifluoromethylated products were then transformed diastereoselectively to α-CF3 β-hydroxyesters with two adjacent quaternary stereocenters via a Grignard reaction. |
