新型含三氟甲磺酸酯的三蝶烯衍生物的合成

本文以廉价易得的1, 8-二羟基蒽醌和1, 4-二羟基蒽醌为起始原料，设计不同的路线，先制备出关键中间产物1, 8, 13, 16-四羟基三蝶烯和1, 4, 5, 8-四羟基三蝶烯，后分别与三氟甲磺酸酐发生酯化反应，得到1, 8, 13, 16-四(三氟甲磺酰基)氧基]三蝶烯和1, 4, 5, 8-四(三氟甲磺酰基)氧基]三蝶烯，产率分别为46.2%、70.5%。产物的结构通过ESI-HMS和NMR (1H NMR、19F NMR)表征。该合成方法简单、高效，中间产物稳定，可为以三蝶烯为骨架的三氟甲磺酸芳香酯的工业化生产提供参考。

Synthesis of Novel Triflic Acid Derivatives Containing Triflate

In this paper, the cheap and easily available 1, 8-dihydroxyanthraquinone and 1, 4-dihydroxyanthraquinone were used as starting materials, and different routes were designed to prepare the key intermediate product 1, 8, 13, 16-tetrahydroxytriptycene. and 1, 4, 5, 8-tetrahydroxytriptycene, and then esterified with trifluoromethanesulfonic anhydride to obtain 1, 8, 13, 16-tetra(trifluoromethanesulfonyl)oxy]triptycene and 1, 4, 13, 16-tetra(trifluoromethanesulfonyl)oxy]triptycene,the yields were 46.2% and 70.5%, respectively. The structure of the products were characterized by ESI-HMS and NMR (1H NMR, 19F NMR). The synthesis method is simple, efficient, and the intermediate products are stable, which can provide a reference for the industrialized production of the aryl trifluoromethanesulfonate with triptycene as the skeleton.
