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
General procedure: A mixture of acetophenone 4a (120 mg, 1.0 mmol), iodine (254 mg, 1.0 mmol), and CuO (88 mg, 1.1 mmol) in anhydrous methanol (10 mL) was heated at reflux, after disappearance of the reactant (1-12 h, monitored by TLC), 1,2-diamines 2a (108 mg, 1.0 mmol) and K3PO4*3H2O (266 mg, 1.0 mmol) was added and the mixture was stirred for 12 h at 40 C. The solvent was removed under reduced pressure, and 50 mL water was added to mixture, extracted with EtOAc three times (3¡Á50 mL). The extract was washed with Na2S2O3, dried over anhydrous Na2SO4, and concentrated in vacuo. The residue was purified by column chromatography on silica gel using petroleum ether/EtOAc as the eluent to give the expected products 6aa as pale yellow solid, (80% yield).
As the paragraph descriping shows that 2879-20-1 is playing an increasingly important role.
