    优化 Chromone-2-羧酸的合成路线:加速发现基于 Chromone 的多靶标配体
    摘要:
    6-溴色酮-2-羧酸 (3) 是通过微波辅助工艺合成的。反应的优化通过不同的参数进行,例如碱类型/试剂当量数、溶剂、温度和反应时间。反应产率提高到87%。新的合成路线是通用的,因为以良好的产率 (54-93%) 获得了几种色酮-2-羧酸(化合物 4B-10B)。仅在硝基取代基(化合物 11B)的情况下,获得酯而不是所需的羧酸。按照这种合成路线,色酮羧酸可以以高纯度获得,而无需通过柱色谱进行繁琐和昂贵的纯化过程。反应安全、经济、快速、稳健,可用于基于chromone scaffold的简洁、面向多样性的文库开发。整个研究可以看作是加快发现基于色酮的多靶标配体的一步。
