With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.1593-08-4,2-Formylquinoxaline,as a common compound, the synthetic route is as follows.
1593-08-4, This procedure is based on our previous report27 and vogels procedure36. To a conical flask containing NaOH solution (1.5eq, 10 mL H2O) was added substituted acetophenones (1mmole) in ethanol (10 mL), and the reaction mixture was stirred for 10 minutes to allow enolate formation, to this was added quinoxaline-2- carbaldehyde 1 (1mmole) and the reaction mixture was stirred till completion. After completion of the reaction, as monitored by TLC the reaction mixture was poured in an ice bath and was acidified using conc. HCl. The solid obtained was then filtered, dried and recrystallized using Ethanol. The quinoxalinyl chalcone 2a-n were then characterized using IR, NMR (1H, 13C) and HR-MS spectroscopy. The purity was checked by HPLC measurements using mobile phase consisting methanol and water in the ratio 90:10.
The synthetic route of 1593-08-4 has been constantly updated, and we look forward to future research findings.
