Abstract: [Figure not available: see fulltext.]Indenoquinolinones have been synthesized from 2-haloquinoline-3-carbaldehyde through Pd-mediated simultaneous C–H (aldehyde) and C–X bond activation. DFT studies were performed to investigate the mechanistic pathway, and in situ UV–Vis studies indicate the presence of Pd(II) intermediate species. Aryne ligated Pd complex is actual intermediate in these reactions. Ligation of reactive aryne to Pd reduces probability of side reactions. Graphic abstract: [Figure not available: see fulltext.]

A series of some substituted diethyl 4-(2-chloroquinolin-3-yl)-2,6-dimethylpyridine-3,5-dicarboxylates has been synthesized from substituted diethyl4-(2-chloroquinolin-3-yl)-1,4-dihydro-2,6-dimethylpyridine-3,5-dicarboxylates (1,4-DHPs) by treating the latter with SiO2–HNO3 which proved to be a better oxidant in terms of product yield, reaction time, and cost. Further, these compounds were screened for their antimicrobial activity. All the diethyl 4-(2-chloroquinolin-3-yl)-2,6-dimethylpyridine-3,5-dicarboxylates exhibited more potent activities than the corresponding 1,4-DHPs. Further, docking simulation of the most active and least active compounds 3e and 2e into Escherichia coli topoisomerase II DNA Gyrase B was also performed.

Azetidin-2-one fused 2-chloro-3-formyl quinolines derivatives, 3-chloro-4-(2-chloro-8/7/6-methoxyquinolin-3-yl)-1-(2,4-dinitro/4-nitro phenylamino)azetidin-2-one,3-chloro-4-(2-chloro-8/7/6-chloroquinolin-3-yl)-1-(2,4-dinitro/4-nitro phenylamino)azetidin-2-one, 3-chloro-4-(2-chloro-8/7/6-methylquinolin-3-yl)-1-(2,4-dinitro/4-nitrophenylamino) azetidin-2-one were synthesized by four steps, respectively from N-arylacetamides, 2-chloro-3-formyl quinolines, 2,4-dinitro/4-nitro phenyl hydrazine reflux with chloroacetyl chloride and triethyl amine. However yields of quinolines having electron donating groups in all cases. The structures of the synthesized compounds have been established on the basis of physical and spectral data. The antibacterial and antifungal activity of these compounds was tested by filter paper disc method against Staphylococcus aureus (MTCC96), Escherichia coli (MTCC722) and Candida albicans (MTCC183). The results showed that azetidin-2-one fused 2-chloro-3-formyl quinolines derivatives are better in inhibiting the growth of both types of organisms. Compounds AZT b2, AZT b3 to AZT g2, AZT g3 were found to be more potent compared to standard drug.

For the first time, synthesis of AB ring core of camptothecin synthons such as (2-chloroquinolin-3-yl)methanols (Va-Vg) using zinc oxide nanoparticles is reported. The desired attractive products were obtained in high yields, short reaction time, using a simple work-up procedure with the purification of products by non-chromatographic methods.

Ethyl 3-oxo-3-{2-[(5-substituted-3-phenyl-1H-indol-2-yl)carbonyl] hydrazinyl}propanoates 5a-b were synthesized according to the literature method. These on further reaction with substituted-2-hydroxy-3-formylquinolines 3a-e yielded 5-substituted-Nβ-(2-oxo-2H-pyrano[2,3-b]quinoline-3- carbonyl)-3-phenyl-1H-indole-2-carbohydrazides 6a-j. Structures of the all the newly synthesized compounds were confirmed by spectral data. All these compounds have been screened for their antibacterial activity against Staphylococcus aureus, Escherichia coli and Bacillus subtilus, antifungal activity against Aspergillus niger and Candida albicans and antituberculosis activity against Mycobacterium tuberculosis (H37Rv).

Vilsmeier-Haack reagent: A facile synthesis of 2-chloro-3-formylquinolines from N-arylacetamides and transformation into different functionalities
Srivastava, Ambika,Singh
, p. 1868 - 1875 (2007/10/03)
A simple and regioselective synthesis of 2-chloro-3-formylquinolines through Vilsmeier-Haack cyclisation of N-arylacetamides has been reported. The cyclisation is facilitated by N-arylacetamides bearing electron donating groups at m-position. However, yields of quinolines having electron donating groups are good in all cases. Further, the nucleophilic substitution reaction of the quinolines is also investigated. Similarly, the formyl group in the quinolines is subjected to further transformation into cyano (CAN-NH3) and alkoxycarbonyl (NIS-K2CO3/alcohols) groups to afford corresponding 3-cyano and 3-alkoxycarbonylquinolines, respectively.

Acetanilides are converted into 2-chloroquinoline-3-carbaldehydes in good yield by the action of Vilsmeier's reagent in phosphoryl chloride solution.The reaction is shown to involve successive conversion of the acetanilide into an imidoyl chloride and then an N-(α-chlorovinyl)aniline.The latter enamine is diformylated at its β-position and subsequently cyclised to the chloroquinolinecarbaldehyde.The diformylated intermediates may be isolated in several cases and separately cyclised with polyphosphoric acid.
