以3-烷氧基苯酚为A（2）型单体，戊二醛为B-4型单体，通过缩合反应成功地合成了一系列新的诺里亚类大环化合物。这些缩合反应使用几种酸作为催化剂在乙醇和CHCl 3中进行。结果发现，这些反应进行的DCC提供可溶性聚合物，低聚物，和诺里亚样梯形大环。结果，成功地以高产率选择性合成了目标诺里亚类大环化合物。
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.
