Synthetic routes to forty-seven dibenzo-16-crown-5 compounds with pendant carboxylic acid groups are reported. When taken together with previously described lariat ether carboxylic acids, these new compounds provide several series with systematic structural variations including changes in the identity and attachment site(s) of one or more lipophilic groups and the length of the spacer that connects
                                    报道了合成47个具有侧链
羧酸基团的二苯并-
16-冠-5化合物的途径。当与先前描述的套索状醚
羧酸一起使用时,这些新化合物提供了几个具有系统结构变化的系列,包括一个或多个亲脂基团的身份和连接位点的变化以及连接
羧酸基团的间隔基的长度聚醚框架。
