With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.88511-37-9,1-(Isoxazol-3-yl)ethanone,as a common compound, the synthetic route is as follows.,88511-37-9
General procedure: To a solution of ketone A in THF cooled to -78 C, LiHMDS (e.g., 0.9 eq, 1.0 M in toluene) is added dropwise, for example using a syringe. The reaction mixture is then allowed to warm to about 0 C, then charged with diethyl oxalate (1.2 eq). At this time, the reaction mixture is warmed to room temperature and stirred at that temperature until judged complete (e.g., using either TLC or LC/MS analysis). Once the reaction is complete (reaction time typically about 45 minutes), the product dione enolate B is used as-is in Step 2, i.e., the cyclization step, without any further purification
The synthetic route of 88511-37-9 has been constantly updated, and we look forward to future research findings.
