This compound belongs to quinoline derivatives. According to its name, it can be seen that the structure contains a quinoline parent nucleus. The quinoline parent nucleus is a nitrogen-containing heterocyclic ring, which is formed by fusing a benzene ring with a pyridine ring.
"1,2-dihydro" indicates that the double bond between the 1 and 2 positions of the quinoline parent nucleus is hydrogenated, and two degrees of unsaturation are missing. "5-chloro" indicates that there is a chlorine atom substitution at the 5 position of the quinoline parent nucleus. "4-hydroxyl" refers to the 4 position of the parent nucleus with a hydroxyl group. "1-methyl" means that there is a methyl substitution at the 1 position. "2-oxo" Table 2 is a carbonyl oxygen atom.
Look at "N-ethyl-N-phenyl-3-formamide" again, this is the 3-position formyl group of the parent nucleus connected to ethyl and phenyl on the nitrogen atom. That is, the 3-position carbonyl group is connected to the nitrogen-containing atom group to form an amide structure, and the nitrogen atom is connected to ethyl and phenyl at the same time.
In summary, the chemical structure of this compound is formed by the quinoline parent nucleus modified by multiple substitutions, and contains chlorine, hydroxyl, methyl, carbonyl and specific amide substituents and other functional groups. Each part is connected in an orderly manner by name to form a unique chemical structure.
