Synthesis of Novel Tris-Crown Ether Structures

Six unique tris-crown ether structures were successfully synthesized from trimethylolpropane triacrylate (TMPTA) with amino- and aza-crown ethers through Michael addition. The crown ethers contained a primary amine group such as 2aminomethyl crown ethers and 4-aminobenzo crown ethers, others contained a secondary amine group, like 1-aza crown ethers.
