2-Aryl- and 2-alkyl-quinolin-4-ones and their N-substituted derivatives have several important biological functions such as the Pseudomonas quinolone signal (PQS) molecule participation in quorum sensing. Herein, we report the synthesis of its biological precursor, 2-heptyl-4-hydroxy-quinoline (HHQ) and possible isosteres of PQS; the C-3 Cl, Br and I analogues. N-Methylation of the iodide was also
2-芳基和2-烷基喹啉-4-酮及其N-取代的衍生物具有几种重要的生物学功能,例如假单胞菌喹诺酮信号(PQS)分子参与群体感应。在本文中,我们报告了其生物前体2-庚基-4-羟基喹啉(HHQ)和PQS可能的等排体的合成;C-3 Cl,Br和I类似物。碘化物的N-甲基化也是可行的,并且该化合物的有用性在Pd催化的交叉偶联反应中得到了证明,因此可以使用多种生物学上重要的分子。还包括PQS的第一晶体结构。
