2879-20-1, 1-(2,3-Dihydrobenzo[b][1,4]dioxin-6-yl)ethanone is a benzodioxans compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated,2879-20-1
General procedure: N-Bromobutanimide (NBS, 356 mg, 2.0 mmol) and 4-Methylbenzenesulfonic acid (PTSA, 344 mg, 2.0 mmol) were added to a well-stirred solution of aryl methyl ketone 8a (240 mg, 2.0 mmol) in anhydrous MeCN (15 mL). The mixture was stirred at room temperature for 1 h, and then refluxed for another 1-2.5 h. After disappearance of aryl methyl ketone 8a (monitored by TLC), the solvent was removed under reduced pressure, then added 50mL water to the mixture, extracted with EtOAc 3 times (3 ¡Á 50 mL). The extract was washed with 10% NaCl solution, dried over anhydrous Na2SO4 and concentrated under reduced pressure. The residue was puried by column chromatography on silica gel to yield the desired product 4a as a white solid in 90% yield.
The synthetic route of 2879-20-1 has been constantly updated, and we look forward to future research findings.
