Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 391-12-8, name is 7-(Trifluoromethyl)isatin, A new synthetic method of this compound is introduced below., Formula: C9H4F3NO2
The above product (163 mg, 0.654 mmol) was dissolved in 3.2 mL of dry dichloromethane, and Dess-Martin periodinane (290 mg, 0.68 mmol) was added to the solution at room temperature. After the reaction mixture was stirred for 30 min at the same temperature, saturated NaHCO3 aqueous solution was added. The mixture was extracted with ethyl acetate, and the extract was washed with brine, and dried over MgSO4. After filtration, the filtrate was concentrated in vacuo and the residue was purified by silica gel column chromatography (hexane/ethyl acetate = 95/5 to 75/25) to obtain the title compound as a white powder (140 mg, 86%).
The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.
