As a common heterocyclic compound, it belongs to benzodioxans compound, name is 2,3-Dihydro-1,4-benzodioxine-6-carboxylic acid, and cas is 4442-54-0, its synthesis route is as follows.,4442-54-0
General procedure: A mixture of compound 9 or 10 (0.11 mmol), O-(7-aza-1H-benzotriazol-1-yl)-N,N,N’,N’-tetramethyluronium hexafluorophosphate (0.21mmol), and N,N-diisopropylethylamine (0.54 mmol) in dry DMF (1.5 mL) was stirred at 0 ¡ãC for 30 min. The appropriate acid (0.16 mmol) was then added. After stirring at room temperature for 1-4 h, the reaction mixture was diluted with saturated aqueous NaHCO3, and extracted with ethyl acetate. The organic layer was washed with brine, dried over anhydrous MgSO4, and concentrated in vacuo. The residue was purified by column chromatography on silica gel eluting with EtOAc-hexane (1:1 to 1:3) to afford the corresponding compounds 11a-o and 12a-c.
With the complex challenges of chemical substances, we look forward to future research findings about 4442-54-0,belong benzodioxans compound
