Novel cyclophanes (9a, b) having eight carboxyl groups on the aromatic rings were designed and synthesized. Macrocyclization of 7a and 7b with 6 was carried out under a high dilution condition to give the corresponding 8a and 8b in 23% and 28% yields, respectively.
我们设计并合成了芳香环上带有八个羧基的新型环烷(9a、b)。在高稀释条件下,7a 和 7b 与 6 进行大环化反应,得到相应的 8a 和 8b,产率分别为 23% 和 28%。
