preparation of these scaffolds is not trivial, involving synthetic routes that require 4,5,9,10-tetrahydropyrene as a key intermediate. Herein, the development and optimization of routes for the synthesis of 2-functionalized pyrene-derived building blocks, with potential to be used as tags in the preparation of fluorescent probes, is described. Additionally, the crystal structures of ethyl 4,5,9,1
y具有形成荧光准分子的倾向,因此这种发色团通常存在于传感器和荧光探针中。2-官能化pyr特别令人感兴趣,但是这些支架的制备并非易事,涉及需要4,5,9,10-四氢py作为关键中间体的合成途径。在此,描述了开发和优化合成2-官能化的-衍生结构单元的途径的方法,该方法具有用作制备荧光探针的标签的潜力。另外,4,5,9,10-四氢-2-py-5-氧戊酸乙酯和2-乙酰基-4,5,9,10-四氢py乙酯的晶体结构揭示了饱和的四氢py环的独特构象。
