A novelN,N‐dibenzyl diaminomethylenemalononitrile organocatalyst efficiently promoted asymmetric Henry reactions of trifluoromethyl enones with nitromethane, affording corresponding highly functionalized products in high yields with excellent enantioselectivities (up to 90%ee). This study is the first to report the successful example of the asymmetric 1,2‐additions of nitromethane to trifluoromethyl enones.
