Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures. A Journal, ACS Sustainable Chemistry & Engineering called Long-Chained Acidic Ionic Liquids-Catalyzed Cyclization of 2-Substituted Aminoaromatics with β-Diketones: A Metal-Free Strategy to Construct Benzoazoles, Author is Miao, Chengxia; Hou, Qin; Wen, Yating; Han, Feng; Li, Zhen; Yang, Lei; Xia, Chun-Gu, which mentions a compound: 6797-13-3, SMILESS is CCC1=NC2=CC=CC=C2O1, Molecular C9H9NO, HPLC of Formula: 6797-13-3.
With long-chained acidic ionic liquids as catalysts, a metal-free, efficient, and universal strategy was developed to synthesize a series of benzoazole compounds through intermol. cyclization of 2-aminophenols/thiophenols/anilines with β-diketones. Compared with traditional ionic liquids, the long-chained ionic liquids with certain surfactivity exhibited better catalytic activities perhaps for micellar action and could be reused at least six times. A mechanism that involves condensation, nucleophilic addition, and C-C bond cleavage was proposed, and the imine compound was recognized as an important intermediate in the reaction.
The article 《Long-Chained Acidic Ionic Liquids-Catalyzed Cyclization of 2-Substituted Aminoaromatics with β-Diketones: A Metal-Free Strategy to Construct Benzoazoles》 also mentions many details about this compound(6797-13-3)HPLC of Formula: 6797-13-3, you can pay attention to it, because details determine success or failure
