Synthesis of Some 2-Aryl- and 23-Diaryl-quinolin-4
1016 CHAPTER 21 • THE CHEMISTRY OF CARBOXYLIC ACID DERIVATIVES 21.8 REACTIONS OF CARBOXYLIC ACID DERIVATIVES WITH NUCLEOPHILES Section 21.7 showed that all carboxylic acid derivatives hydrolyze to carboxylic acids.... A series of 7-substituted-6-ﬂuoro-1-ﬂuoromethyl-4-oxo-4H-[1,3]thiazeto[3,2-a]quinoline-3-carboxylic acid derivatives (2a—l) was prepared and evaluated for antibacterial activity. These compounds were obtained by deacylation of 4-benzoyloxy-2-(1-chloro-2-ﬂuoroethyl)thio-6,7-diﬂuoroquinoline-3-carboxylate (10) and subse- quent intramolecular cyclization followed by substitution with
Heterocycles [h]-Fused Onto 4-Oxoquinoline-3-Carboxylic
acetyl-quinoline-4-carboxylic acids were reacted with various aromatic aldehydes in the presence of basic medium using Claisen-Schmidt condensation in order to afford the corresponding chalcones. The substituted chalcones, on condensation with hydroxylamine hydrochloride in ethanol furnished isoxazoles derivatives. Another quinolines derivative were synthesized in this study by using an aryl... A selection of potential bioactive molecules including alkoxy derivatives of (quinoline-4-ylthio)carboxylic acids using virtual screening has been carried out and their biological activity was determined. The studied substances proved to be low-toxic, biologically active compounds. It was established that 4-thio derivatives of quinoline exhibit pronounced antiradical, antioxidant effects …
