Synthesis and recognition properties of tweezer-shaped anion receptors based on acylhydrazone units was written by Zou, Linbo;Pan, Dingwu;Yan, Bairen;Tan, Zan;Lu, Xinyang;Du, Huan;Bao, Xiaoping. And the article was included in Huaxue Tongbao in 2015.Application of 1646-27-1 This article mentions the following:
An indole-acylhydrazone-based tweezer-shaped anion receptor (I) was designed and synthesized, and it displayed a selective recognition for biol. important F–, AcO– and H2PO4– (Ka > 104 L/mol with a 1:1 stoichiometry) in CH3CN containing 1 (vol)% DMSO. However, no binding interaction was observed for other anions such as Cl–, Br–, I–, NO3–, N3–, HSO4– and ClO4–. Compared with 1, reference compound 2 (end groups were benzofuran) showed a decreased affinity towards the above three anions, especially for H2PO4–. 1H NMR titration experiments indicated that cooperative utilization of indole NHs and amide NHs within 1 led to it strong binding with anions. In the experiment, the researchers used many compounds, for example, Methyl benzofuran-2-carboxylate (cas: 1646-27-1Application of 1646-27-1).
Methyl benzofuran-2-carboxylate (cas: 1646-27-1) belongs to benzofurans derivatives. Benzofuran is the “”parent”” of many related compounds with more complex structures. For example, psoralen is a benzofuran derivative that occurs in several plants. In nature, benzofurans have occupied an important role among the plant phenols & several pharmacologically active compounds.Application of 1646-27-1
