Organocatalyzed Michael addition of N‐substituted tetramic acids to nitroalkene acceptors followed by O‐alkylation gave polyfunctionalized tetramic acid (31 examples, 59–94% ee). The enantioselectivity of the product was influenced by the N‐substituent of the substrate. Quantum chemical methods provided the mechanistic insights of the studied transformation. The preferred reaction pathway follows...
