, p. 4600 - 4604 (2007)
In the palladium-catalyzed reaction of acrylates, C-N bond activation and acetalization occurred under different conditions. Described herein is a highly efficient palladium-catalyzed C-N bond activation reaction and subsequent new C-N bond formation to directly construct β-amino acids from triethylamine and acrylate esters in isolated yields of up to 95%.

Here, we have demonstrated the Michael addition of active methylene compounds, aromatic/aliphatic amines, thiols and alcohols to conjugated alkenes using magnetic nano-NiFe2O4 as reusable catalyst in water. Nano-NiFe2O4 efficiently catalyzed the formation of C-C and C-X (X = N, S, O etc.) bond through 1,4-addition reactions.

A biomaterial supported organocatalyst, readily synthesized by the reaction of chemically modified sulfonic group containing expanded corn starch with pyridine exhibited excellent catalytic activity for the synthesis of β-amino carbonyls in excellent yields via aza-Michael addition of amines to electron deficient alkenes. A remarkable enhancement in the reaction rates was observed with the prepared bifunctional organocatalyst in comparison to the either starch grafted sulfonic acid or the corresponding homogeneous pyridinium p-toluenesulfonate.
