摘要
The asymmetric double Michael additions of curcumins to nitroalkenes to afford highly functionalized cyclohexanones have been carried out for the first time. A combination of a dihydrocinchonine-thiourea organocatalyst and K2CO3 was found to be the most effective in obtaining the desired cyclohexanones in good yield, diastereoselectivity and enantioselectivity.
