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. 52351-75-4, name is 6-Methoxyindoline-2,3-dione, A new synthetic method of this compound is introduced below., name: 6-Methoxyindoline-2,3-dione
General procedure: A mixture of 1 (0.4 mmol), 2 (0.4 mmol), Na2CO3 (0.8 mmol) and TBHP (0.4 mmol) in DMF (4 mL) was stirred at rt for 2 h. Then, the mixture was poured into ice-water, acidified with 1 N HCl aq. (6 mL). The mixture was extracted with ethyl acetate (20 mL x 3). The combined organic layer was dried over anhydrous Na2SO4 and concentrated in vacuo. The residue was purified by silica gel flash column chromatography to give desired products.
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.
