With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.2879-20-1,1-(2,3-Dihydrobenzo[b][1,4]dioxin-6-yl)ethanone,as a common compound, the synthetic route is as follows.
General procedure: Finely powdered CuO (0.8 g, 10.0 mmol) and I2 (2.53 g, 10.0 mmol) were added to a solution of aryl methyl ketone 9a (1.2 g, 10.0 mmol) in anhydrous MeOH (20 mL). The mixture was refluxed for 1-2.5 h. After disappearance of aryl methyl ketone 9a (monitored by TLC), the mixture was filtered and the solvent was removed under reduced pressure. The residue was poured into 10% Na2S2O3 solution (50 mL), the mixture was extracted with EtOAc (3 ¡Á 50 mL), and the organic layer was dried (Na2SO4). Removal of the solvent and purification of the residue by column chromatography gave the desired product 1a in 96% yield.
2879-20-1, The synthetic route of 2879-20-1 has been constantly updated, and we look forward to future research findings.
