achieved a new and facile synthesis of a combinatorial library of its tetra- and persubstituted derivatives by trifluoracetic acid catalyzed condensation of a group of 5-aminopyrazoles and a group of α-oxoketene dithioacetals. Furthermore, we demonstrated structural modification of the products via reductive desulfurization, hydrolysis of the ester, and Suzuki coupling of the bromo derivative with aryl
吡唑并[3,4- b ]吡啶是一种具有药用价值的结构。我们通过三氟乙酸催化一组 5-氨基吡唑和一组 α-氧代烯酮二硫缩醛的缩合,实现了其四取代和全取代衍生物的组合库的新且简便的合成。此外,我们还证明了通过还原脱硫、酯水解以及溴代衍生物与芳基硼酸的 Suzuki 偶联对产品进行结构修饰。一些产品针对结核分枝杆菌H37Rv 菌株进行了体外微孔板 Alamar Blue 测定 (MABA) 测定,并通过与结核分枝杆菌(MTBPS)的泛酸合成酶结合进行了计算机分析。结果表明,吡唑并[3,4- b ]吡啶与N(1)CH 3、C(3)C 6 H 5、C(4) p CH 3 C 6 H 5、C(5)CO 2 Et , C(6)SMe 取代表现出有希望的抗结核活性。
