We report here the efficient synthesis of 6,6′-diamido-2,2′-dipicolylamines (DA-DPAs) which could be applied to phosphate anion sensing via pre-formed metal complexes. The design was based on the retrosynthetic analysis. This strategy enabled us to achieve the functionalized DA-DPAs in satisfactory yields with high purity using the Boekelheide rearrangement. Meanwhile, all the intermediates could be
我们在此报告了 6,6'-二氨基-2,2'-二吡啶甲胺 (DA-DPA) 的有效合成,其可通过预先形成的金属配合物应用于磷酸盐阴离子传感。该设计基于逆合成分析。该策略使我们能够使用 Boekelheide 重排以令人满意的收率和高纯度实现功能化 DA-DPA。同时,所有的中间体都可以很容易地通过硅胶柱色谱进行纯化。
