Name is 1-(2,3-Dihydrobenzo[b][1,4]dioxin-6-yl)ethanone, as a common heterocyclic compound, it belongs to benzodioxans compound, and cas is 2879-20-1, its synthesis route is as follows.,2879-20-1
To a solution of dithiocarbonic acid O-benzyl ester S-methyl ester (0.99 g) and 1-(2,3-dihydrobenzo[1,4]dioxin-6-yl)ethanone (0.89 g) in toluene (20 mL) was added sodium amide (0.39 g) at room temperature, and the mixture was stirred at room temperature for 3 days. A hydrochloric acid aqueous solution (2 mol/L) was added to the reaction mixture, and the mixture was extracted with diethyl ether. The organic layer was washed with brine and dried over anhydrous magnesium sulfate, and the solvent was removed under reduced pressure. Acetonitrile (5 mL), triethylamine (2.5 g) and isopropylhydrazine hydrochloride (0.55 g) were added to the residue, and the mixture was stirred at room temperature overnight. Water and diethyl ether was added to the reaction mixture, and the organic layer was separated. The organic layer was washed with brine and dried over anhydrous magnesium sulfate, and the solvent was removed under reduced pressure. The residue was purified by column chromatography on aminopropylated silica gel (eluent: dichloromethane) to give the title compound (1.8 g).
With the complex challenges of chemical substances, we look forward to future research findings about 1-(2,3-Dihydrobenzo[b][1,4]dioxin-6-yl)ethanone
