| Application | O-amino acetophenone is an important fine chemical intermediate, such as the preparation of a high-acidity ionic liquid for the catalytic synthesis of 2-aryl -2, 3-dihydro-4 (1H)-quinolinone derivatives, which belongs to the technical field of chemical material preparation. A method for the catalytic synthesis of 2-aryl -2, 3-dihydro-4 (1H)-quinolinone derivatives by a high-acidity ionic liquid of the present invention. The method uses o-aminophenone and aromatic aldehydes as reaction raw materials to synthesize 2-aryl -2, 3-dihydro-4 (1H)-quinolinone derivatives under the catalysis of a high-acidity ionic liquid catalyst, by selecting specific ionic liquid with high acidity as catalyst and optimizing the reaction process parameters, the shortcomings of the catalyst in the existing synthesis process, such as large usage, relatively poor recycling performance, complex product purification process and further improvement of the product yield, can be effectively overcome. |
| Use | O-amino acetophenone is an aromatic compound containing a ketone substituted by an alkyl group and a phenyl group. When used to detect infection of Pseudomonas aeruginosa in cystic fibrosis lung, anthraninophenone can be used as a biological marker (breath biomarker) of the respiratory system. Used as oil-soluble color forming agent intermediate |
| Biological activity | 2 '-Aminoacetophenone is an aromatic compound containing a ketone substituted by an alkyl group and a phenyl group. 2 '-Aminoacetophenone can be used as a respiratory biomarker (respiratory biomarker) when used to detect Pseudomonas aeruginosa infection in cystic fibrosis lung. |
