Synthesis of Noria-like Macrocycles Containing Alkoxy Groups based on a Dynamic Covalent Chemistry (DCC) System by the A(2)+B-4 Condensation
We succeeded in the synthesis of new noria-like macrocycles by condensation of 3-alkoxyphenol as A(2) type monomers, and pentanedial as B-4 type monomer. These condensation reactions were performed using several acids as catalysts in ethanol and CHCl3. It was found that these reactions proceeded by DCC to afford soluble polymers, oligomers, and noria-like ladder macrocycles. As the result, the selective synthesis of the targeted noria-like macrocycles was achieved successfully in high yields.
