Tris(2-aminoethyl)-amine, TREN based tris-ureas (1a–1d) and tris-thiourea (1e) have been explored towards a wide range of catalytic Michael addition reactions. These tris-ureas, 1a–1d efficiently catalyze the addition reaction of β-nitro styrenes (2a–2d)

We have reported that Amberlite IRA900F (Amb-F) is an efficient metal-free catalyst for the activation of Si-N and Si-O bonds and a mild base in a variety of organic transformations under solvent-free conditions, such as the addition of TMSN3 to (E)-2-aryl-1-cyano-1-nitroethenes, nitriles, α,β-unsaturated acids and their esters, and the addition of dimethylsilyl ketene acetal and ethyl nitroacetate to β-nitrostyrenes.
