Recoverable hybrid materials for heterogeneous enantioselective organocatalyzed Michael addition reaction. Developed through the ready intercalation of α-amino acids and α,β-dipeptides into reconstructed hydrotalcite (Mg/Al) by means of sustainable technics such as mechanochemical and ultrasound activation. The conjugate addition of aldehydes to maleimides under mild and solvent free conditions proceeded with high yield and excellent enantioselectivity up to 99 : 1 e.r.
