of antimicrobial 2-alkyl-4(1H)-quinolones, i.e., 4-hydroxy-3-methyl-2-alkenylquinolines (HMAQs) and their N-oxide derivatives (HMAQNOs). Herein, we report the synthesis of a series of six HMAQs and HMAQNOs featuring a trans-Δ2 double bond at the C2-alkyl chain. The quinolone scaffold was obtained via the Conrad–Limpach approach, while the (E)-2-alkenyl chain was inserted throughSuzuki–Miyaura cross-coupling

N-Myristoyltransferase (NMT) is a prospective drug target against parasitic protozoa. Herein we report the successful discovery of a series of Plasmodium vivax NMT inhibitors by high-throughput screening. A high-resolution crystal structure of the hit compound in complex with NMT was obtained, allowing understanding of its novelbindingmode. A set of analogues was designed and tested to define the
A [4 + 2] annulation involving cascade Knoevenagel, aza-Wittig and dehydrofluorination reactions is developed for the synthesis of substituted quinolin-4-ols including analogs bearing CF2H, CF3, and C2F5 groups. This simple and highly efficient method is also applicable for the synthesis of substituted quinolines. A number of reported biologically active compounds can be readily prepared by this one-pot
开发了一种包括级联Knoevenagel,aza-Wittig和脱氟化氢反应的[4 + 2]环合反应,用于合成取代的喹啉-4-醇,包括带有CF 2 H,CF 3和C 2 F 5基团的类似物。这种简单而高效的方法也适用于取代喹啉的合成。通过一锅法合成可以容易地制备许多报道的生物活性化合物。新反应过程的绿色化学指标分析提供了令人满意的结果。
