Organocatalytic Michael additions of cyclopentane-1,2-dione to different nitroolefins
have been investigated. Cyclopentane-1,2-dione undergoes an organocatalytic reaction
with substituted nitroolefins giving 3-substituted products in good to high yields
(48–97%) and good stereoselectivity (up to 76% ee).
Key words
Michael addition - asymmetric synthesis - asymmetric catalysis - enantioselectivity
