Synthesis, Characterization and Conformational Analysis of Two Novel 4(1H)‑Quinolinones

Quinolinones are a class of organic compounds known as alkaloids found in several plants and also can be synthesized. Their large use in therapies regards their wide biological potential like antitumor, psychiatric and neurological agents. Two substances were structurally characterized: (E)-3-(2-nitrobenzylidene)-2-(4-methoxyphenyl)-1-(phenylsulfonyl)-2,3-dihydroquinolin-4(1H)‑one (NMQ), and (E)-3-(2-chlorobenzylidene)-2-(2-methoxyphenyl)-1-(phenylsulfonyl)-2,3‑dihydroquinolin-4(1H)-one (CMQ). These compounds were synthesized, crystallized, characterized by single crystal X-ray diffraction...
