Abstract

The incorporation of fluorinated moieties into organic structures is a particularly powerful approach for generating compounds with useful biological applications in industry, pharmacology, and agriculture. Here, the recently developed reagent-CF HCHN -selectively esterifies carboxyl groups on organic molecules in the presence of other polar functional groups. The reaction is remarkably simple, proceeding at room temperature in chloroform without addition of a catalyst. The procedure allows "last-step" incorporation of a fluorinated ester moiety into organic structures, including bioorganic molecules such as peptides and proteins. The fluorinated ester can subsequently function as a F-probe in biomolecules, thereby enabling molecular size determination by diffusion F NMR experiments.

摘要

将氟化基团引入有机结构是一种特别有效的方法,可用于生成在工业、药理学和农业中具有有用生物应用的化合物。在这里,最近开发的试剂-CF HCHN -在其他极性官能团存在下选择性地酯化有机分子上的羧基。该反应非常简单,在室温下于氯仿中进行,无需添加催化剂。该方法允许将氟化酯部分“最后一步”引入有机结构,包括肽和蛋白质等生物有机分子。氟化酯随后可作为生物分子中的F探针,从而通过扩散F NMR实验确定分子大小。
