DABCO Catalyzed One-Pot Synthesis of Ester Derivatives of Tris (2-Aminoethyl)amine

Tris (2-aminoethyl) amine (Tren) is a commercially available tripodal amine. Tren has been widely used as a ligand in the preparation of metal complexes. Tris (2-aminoethyl) amine (Tren)-based esters have been synthesized in a single-pot-reaction of tren with six equivalent each of alkyl acrylates, 3-trimethoxysilyl propyl methacrylate and 2-hydroxyethylmethacrylate in presence of 10 mol% DABCO in mild conditions. The higher yield of the product was obtained in case of alkyl acrylates. The reaction was accomplished at room temperature and in a short reaction time. All synthesized compounds were characterized by IR, UV, 1H NMR, 13C NMR, GC-mass and elemental analysis.
