摘要
A catalytic enantioselective MukaiyamaMichael reaction of 2-enoylpyridine N-oxides has been developed using a simple bis(oxazoline)-copper complex. A variety of silyl enol ethers undergo smooth Michael addition with 2-enoylpyridine N-oxides to furnish the corresponding Michael adducts in high yields with high enantioselectivities (up to 97% ee).
