The reaction of various substituted 24-dichloroquinolines with methyl 4-(4-hydroxyphenyl)-2-methyl-5-oxo-1,4,5,6,7,8-hexahydroquinoline-3-carboxylate has been carried out in the presence of powdered K2CO3 as a mild and efficient base at controlled temperature leading to novel 2-chloroquinoline-based polyhydroquinoline with high regioselectivity. All the synthesized compounds were characterized through IR, NMR, and mass spectral data. © 2013 Springer Science+Business Media Dordrecht.

A rapid microwave assisted synthesis of 1-(6-chloro-2-methyl-4-phenylquinolin-3-yl)-3-(aryl)prop-2-en-1-ones and their anti bacterial and anti fungal evaluation

The 4-hydroxy-3-(3-arylacryloyl)quinolin-2(1H)-ones were synthesized from 3-acetyl-4-hydroxyquinolin-2(1H)-one by microwave assisted synthesis, which in turn converted into their corresponding 3-(4,5-dihydro-5-aryl)isoxazol-3-yl)-4-hydroxyquinolin-2(1H)-ones and 3-(4-styryl)isoxazolo[4,5-c]quinolin-4(5H)-one derivatives. © 2011

Synthesis and characterization of new 3-(4,5-dihydro-5-aryl)isoxazol-3-yl)-4-hydroxyquinolin-2(1H)-ones and 3-(4-styryl)isoxazolo[4,5-c]quinolin-4(5H)-one derivatives

Highly regioselective reaction of some substituted 2,4-dichloroquinolines with symmetrical 1,4-dihydropyridines, leading to novel quinoline derivatives of DHPs, has been achieved in the presence of powdered K2CO 3, as a mild and efficient base, at moderate temperature. All the synthesized compounds were characterized by use of IR, NMR, and mass spectral data. © 2013 Springer Science+Business Media Dordrecht.

Regioselective synthesis of novel 2-chloroquinoline derivatives of 1,4-dihydropyridines

A series of quinoline-based coumarin derivatives have been synthesized by one pot dehydrochlorination of 2,4-dichloroquinolines (1a-g); 7-hydroxy-4-methyl-2H-chromen-2-one (2) under ultrasonic irradiation method with high regio selectivity. All the synthesized compounds were characterized through spectral data and screened against representative antibacterial and antioxidant activities. Some of the compounds are found to be equipotent or more potent than that of standard drugs. Molecular docking studies show that the binding energy value of the compounds is very less than that of standard chloroquine and amodiaquine drugs. © 2012 Springer Science+Business Media New York.

Ultrasound-promoted synthesis, biological evaluation and molecular docking of novel 7-(2-chloroquinolin-4-yloxy)-4-methyl-2H-chromen-2-one derivatives

Ultrasound-promoted reaction of substituted 2,4-dichloroquinolines (1) with ethyl 4-(3-hydroxyphenyl)-6-methyl-2-oxo-1,2,3,4-tetrahydropyrimidine-5- carboxylate (2) in the presence of K2CO3 as mild base at moderate temperatures leads to 2-chloroquinolin-4-pyrimidine carboxylate derivatives (3) with high regioselectivity. All the compounds synthesized were characterized by use of spectral data and screened for their antibacterial activity against two Gram-positive (Staphylococcus aureus, Bacillus cereus) and two Gram-negative (Escherichia coli and Pseudomonas aeruginosa) bacteria. Activity was moderate. © 2012 Springer Science+Business Media B.V.
