In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called N-Heterocyclic carbene copper catalyzed quinoline synthesis from 2-aminobenzyl alcohols and ketones using DMSO as an oxidant at room temperature, published in 2019, which mentions a compound: 20028-53-9, Name is 2-Amino-5-chlorobenzaldehyde, Molecular C7H6ClNO, HPLC of Formula: 20028-53-9.
A facile and practical process for the synthesis of quinolines through an N-heterocyclic carbene copper catalyzed indirect Friedlander reaction from 2-aminobenzyl alc. and aryl ketones using DMSO as an oxidant at room temperature is reported. The quinolines, e.g., I (R1 = 4-MeC6H4, 2-ClC6H4, 3-thienyl, etc., R2 = H; R1 = Ph, R2 = Me), were synthesized in acceptable yields.
As far as I know, this compound(20028-53-9)HPLC of Formula: 20028-53-9 can be applied in many ways, which is helpful for the development of experiments. Therefore many people are doing relevant researches.
