4442-53-9, 2,3-Dihydrobenzo[b][1,4]dioxine-5-carboxylic acid is a benzodioxans compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
General procedure: Method B: SOCl2 (10mL) was added to a stirred solution of compound 3 (20mmol) in anhydrous DMF (50mL). The reaction solution was allowed to stir at room temperature for approximately 4h. Then, active compound 4 (15mmol) and metronidazole (15mmol) were dissolved in CH2Cl2 followed by drop wise addition triethylamine and compound 5 was obtained with yield of 85percent. Compound 5 (10mmol), different substituted benzaldehydes (12mmol) and NaOH (15mmol) were dissolved in DMSO (30mL) at room temperature. The appropriate amount of water was then added in the residue and filtered. The resulting solid was collected and washed with cold water, dried and crystallized from anhydrous ethanol to get the desired compounds. All of the synthetic compounds gave satisfactory analytical and spectroscopic data, which were in full accordance with their depicted structures.
4442-53-9 2,3-Dihydrobenzo[b][1,4]dioxine-5-carboxylic acid 78184, abenzodioxans compound, is more and more widely used in various.
