  摘要：

  本文描述了一种高效的选择性氧化C–H活化/乙酰氧基化协议，适用于一系列连接有2-芳基/杂芳基/噻吩基的二氢喹啉酮，使用醋酸钯作为催化剂，碘苯二乙酸作为氧化剂。所有这些反应在立体障碍较小且电子性质良好的C–H键上进行良好，生成相应的邻位乙酰氧基化衍生物，收率良好。此外，嵌入噻吩基的二氢喹啉酮的乙酰氧基化反应导致产生单一的区域异构体，乙酰氧基在噻吩基部分的C-2位上。然而，当噻吩单元的C-2位被阻塞时，乙酰氧基则会独占性地安装在C-4位上。此外，我们注意到，二氢喹啉-5(6H)-酮-肟的乙酰氧基化并未改变配体的优先性，仍然生成邻位乙酰氧基化产物。

  DBU-catalysed metal-free domino reaction strategy has been developed for the facile synthesis of dihydro-6H-quinoline-5-ones. This protocol employs a very expedient route to the synthesis of pyridine frameworks using β-chloro-α,β-unsaturated aldehydes, 1,3-diketones, and ammonium acetate in ethanol : water (1 : 1) solvent under eco-friendly conditions. Diverse types of acyclic and cyclic β-chloro-α,β-unsaturated

  已经开发了一种DBU催化的无金属多米诺反应策略，可轻松合成二氢-6 H-喹啉-5-酮。该方案采用非常方便的途径，在生态友好的条件下，在乙醇：水（1：1）的溶剂中，使用β-氯-α，β-不饱和醛，1，3-二酮和乙酸铵合成吡啶骨架。使用多种类型的无环和环状β-氯-α，β-不饱和醛来获得各种二氢-6 H-喹啉-5-酮。通过分离中间体化合物来建立多米诺反应的机理，将其进行下一步反应以获得目标产物。中间体的结构由光谱和单晶XRD研究确定。大部分合成的二氢-6发现H-喹啉-5-酮衍生物对HeLa细胞系具有细胞毒性，在MTT分析中显示出深远的细胞毒性。DNA片段化验结果表明，处理组中没有片段化的DNA，这表明该化合物不会诱导HeLa细胞凋亡。在大多数情况下，尽管在某些情况下也观察到坏死，但从荧光显微镜研究中可明显看到自噬细胞死亡。

  The reaction of the iminophosphorane derived from 3-azidocyclohexen-2-enone with substituted cinnamyl aldehydes affords 2-aryl-tetrahydroquinoline derivatives, which are easily converted into 2-arylquinolines. By contrast, iminophosphorane derived from 2-azidocyclohex-2-enone reacts only with α,β-unsaturated aldehydes without substituent at β-position to give 5,6-dihydro-8(7H)quinolinones. The iminophosphorane

  We, herein, describe the synthesis of a series of novel aryl tethered 7,8-dihydroquinolin-5(6H)-ylidenehydrazinecarbothioamides 4a-v, which showed in vitro and in vivo antimycobacterial activity against Mycobacterium tuberculosis (Mtb) H37Rv. The intermediates dihydro-6H-quinolin-5-ones 3a-v were synthesized from beta-enaminones, reacting with cyclochexane-1,3-dione/5,5-dimethylcyclohexane-1,3-dione and ammonium acetate using a modified Bohlmann-Rahtz reaction conditions. They were further reacted with thiosemicarbazide to give the respective hydrazine carbothioamides 4a-v. All the new analogues 4a-v, were characterized by their NMR and mass spectral data analysis. Among the twenty-two compounds screened for in vitro antimycobacterial activity against Mycobacterium tuberculosis H37Rv (ATCC27294), two compounds, 4e and 4j, exhibited the highest inhibition with an MIC of 0.39 mu g/mL. Compounds 4a, 4g, and 4k were found to inhibit Mtb at an MIC of 0.78 mu g/mL. Hydrazinecarbothioamides 4a-k, exhibited enhanced activity than dihydroquinolinones 3a-k. The observed increase in potency provides a clear evidence that hydrazinecarbothioamide is a potential pharmacophore, collectively imparting synergistic effect in enhancing antitubercular activity of the dihydroquinolinone core. The in vivo (Zebra fish) antimycobacterial screening of the in vitro active molecules led to the identification of a hit compound, 4j, with significant activity in the Mtb nutrient starvation model (2.2-fold reduction). Docking studies of 4j showed a hydrogen bond with the P156 residue of the protein.
