In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Tricyclic heteroaromatic ring systems. II. A convenient synthesis of 1H-pyrrolo[3,2-c]quinolines, published in 1978-09-30, which mentions a compound: 18436-73-2, mainly applied to pyrroloquinoline; quinolinyl hydrazone cyclization, Reference of 4-Chloro-8-methylquinoline.
Quinol-4-yl hydrazones I (R = H, Me, Et; R1 = Me, Ph, Et; RR1 = (CH2)n, n = 3, 4; R2 = H, Me; R3 = H, 6-, 7-, 8-Cl, 6-, 7-, 8-Me, 6-, 7-, 8-MeO) on heating in high boiling solvents undergo cyclizations to give 1H-pyrrolo[3,2-c]quinolines II in good yields. Some of these I were alkylated to provide their N-alkyl derivatives
As far as I know, this compound(18436-73-2)Reference of 4-Chloro-8-methylquinoline can be applied in many ways, which is helpful for the development of experiments. Therefore many people are doing relevant researches.
