The first general catalytic asymmetric bromination and chlorination of beta-ketoesters has been developed. The reactions proceed for both acyclic and cyclic beta-ketoesters catalyzed by chiral bisoxazolinecopper(II) complexes giving the corresponding optically active alpha-bromo- and alpha-chloro-beta-ketoesters in high yields and moderate

The direct aldol reaction of 2-ketoesters catalyzed by chiral bisoxazoline copper(II) complexes has been investigated. First the direct homo-aldol reaction of ethyl pyruvate is reported which proceeds to give diethyl 2-hydroxy-2-methyl-4-oxoglutarate. This was isolated as the more stable optically active
