Michael Addition
The 1,4-addition (or conjugate addition) of resonance-stabilized carbanions. The Michael Addition is thermodynamically controlled; the reaction donors are active methylenes such as malonates and nitroalkanes, and the acceptors are activated olefins such as α,β-unsaturated carbonyl compounds.
Examples:
donors
acceptors

Helical peptide foldamers catalyze Michael addition reactions of nitroalkanes or dialkyl malonates to α,β-unsaturated ketones to give Michael adducts with high enantioselectivities. The amide protons at the N terminus in the α-helical peptide catalyst are crucial for activating Michael donors, while the N-terminal primary amine activates Michael acceptors through the formation of iminium ion intermediates.
