application | 1, 3-dihydroisobenzofuran can be used as an intermediate in organic synthesis and pharmaceutical, mainly used in laboratory research and development processes and chemical production processes. |
Preparation | Et3SiH (4 equiv) was added to a stirred solution of 2-hydroxychalcone derivatives (0.5 mmol, 1 equiv) and InCl3 (0.5 equiv) in anhydrous acetonitrile (2.5 mL). Reflux reaction mixture. Add water to the reaction mixture. Dichloromethane is used to extract the reaction mixture. Wash the combined organic layer with brine. The combined organic layer was dried with anhydrous Na 2 SO 4. Vacuum concentration of each layer. The resulting solution was purified by silica gel column chromatography (petroleum ether/ethyl acetate = 50:1) to obtain 1, 3-dihydroisobenzofuran. |
