    Novel Fluorescent Coumarin Reagents Appending 15-Crown-5 Ether for the Rapid and Self-Catalytic Derivatization of Carboxylic Acids
    摘要:
    研究人员设计并合成了新型含氟香豆素衍生物,并将 15-冠醚作为更活跃的催化位点,用于羧酸的荧光衍生化。从与金属醋酸盐在甲醇中络合的稳定常数(Ks)来看,它们的催化能力优于相应的苯并-15-冠醚-5 型试剂。不过,这些试剂在月桂酸衍生化过程中的反应活性不仅取决于引入的冠醚的催化能力,还取决于冠醚在试剂分子中的附加位置。此外,衍生产物在甲醇和乙腈中的荧光量子产率明显高于 0.8。允许在试剂分子中保留催化剂等特定功能应成为开发优良分析试剂的新策略。

  • Synthesis and Evaluation of Novel Crowned Coumarins as Self-Catalytic Fluorescence Reagents

    Three coumarin reagents carrying crown-ether moieties as catalytic sites for the fluorescence derivatization of carboxylic acids were designed and synthesized. The catalytic abilities of these reagents were evaluated based on the stability constants (Ks) for complexation with metal acetates in methanol. The derivatization reactions of carboxylic acids with these reagents proceeded self-catalytically without crown-ether catalysts, and gave the corresponding coumarin esters in good yields. It was found that their reactivities significantly depended upon the metal-binding ability of the reagent molecules from kinetic treatments of the reactions. The derivatized products showed remarkably high fluorescence quantum yields of above 0.8 in methanol. These results suggested that the functionalization of reagents was a quite useful approach for the development of new-type analytical reagents.

    Novel fluorogenic coumarin derivatives appending 15-crown-5 ether as more active catalytic site were designed and synthesized for the fluorescence derivatization of carboxylic acids. From the stability constants (Ks) for complexation with metal acetates in methanol, it was found that their catalytic abilities were superior to the corresponding benzo-15-crown-5 ether type reagent. However, the reactivity of these reagents in the derivatization of lauric acid was dependent on not only the catalytic ability of the introduced crown-ether but also on the appending position of that in a reagent molecule. Furthermore, the derivatized products showed remarkably high fluorescence quantum yields of above 0.8 in methanol and acetonitrile. Allowing to hold a certain function such as catalyst in a reagent molecule should serve as a new strategy for the development of excellent analytical reagents.
