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: Acetophenone 1a (120 mg, 1.0 mmol), pyridine 2a (158 mg, 2.0 mmol), and iodine (254 mg, 1.0 mmol) were placed in an oven-dried and argon filled Schlenk tube. After addition of anhydrous DMSO (5 mL), the mixture was stirred at 100 C for 36 h. After the reaction completed, the mixture was diluted with water and treated with Na2S2O3 (5% w/w, aq) until the color turned to pale yellow. The mixture was then extracted with CH2Cl2 (3¡Á20 mL), the combined organic extracts were dried over Na2SO4 and concentrated under reduced pressure. The crude product was purified by column chromatography on silica gel (eluent: CH2Cl2/EtOAc=200:1) to afford a yellow solid 3aa (122 mg, 85%).
2879-20-1 1-(2,3-Dihydrobenzo[b][1,4]dioxin-6-yl)ethanone 76143, abenzodioxans compound, is more and more widely used in various.
