Analyzing the synthesis route of 2879-20-1

With the synthetic route has been constantly updated, we look forward to future research findings about 1-(2,3-Dihydrobenzo[b][1,4]dioxin-6-yl)ethanone,belong benzodioxans compound

As a common heterocyclic compound, it belong benzodioxans compound,1-(2,3-Dihydrobenzo[b][1,4]dioxin-6-yl)ethanone,2879-20-1,Molecular formula: C10H10O3,mainly used in chemical industry, its synthesis route is as follows.,2879-20-1

General procedure: The initial carbonyl compound (50mmol) was dissolved/suspended in ethanol (50mL) and magnetically stirred with thiosemicarbazide (50mmol) and catalytic amounts of acetic acid for 8-24hat room temperature. The obtained thiosemicarbazone was filtered, washed with the appropriate solvent (n-hexane, petroleum ether or diethyl ether) and dried under vacuum. Ethyl-bromoacetate (50mmol) was added to a suspension of the intermediate thiosemicarbazone (50mmol) and sodium acetate (50mmol) in methanol (50mL) and the resulting mixture stirred at room temperature for 24-48h. The obtained crude 4-thiazolidinone was poured on ice, filtered or extracted with chloroform (3¡Á30mL) and purified by chromatography (SiO2, ethyl acetate/n-hexane 1/2) to give compounds 1a-58a in high yields. The product (50mmol) was dissolved/suspended in 50mL of anhydrous acetone in the presence of anhydrous potassium carbonate (50mmol), and reacted with equimolar amounts of benzyl bromide for 24-48h. The mixture was poured on ice, filtered or extracted with chloroform (3¡Á50mL) and purified by column chromatography (SiO2, ethyl acetate/n-hexane 1/3) in order to obtain compounds 1b-58b in high yield as previously reported [25,26].

With the synthetic route has been constantly updated, we look forward to future research findings about 1-(2,3-Dihydrobenzo[b][1,4]dioxin-6-yl)ethanone,belong benzodioxans compound
