Application of 2058-72-2, As we all know, there are many different methods for the synthesis of a compound, and people can choose the synthesis method that suits their own laboratory according to the actual situation. 2058-72-2 name is 5-Bromo-1-methylindoline-2,3-dione, This compound is widely used in many fields, so it is necessary to find a new synthetic route. The downstream synthesis method of this compound is introduced below.
General procedure: A solution of carbonyl compounds 1 (0.30 mmol), isatins 2 (0.40 mmol) and 50 mol% Cat. Et2NH (0.15 mmol) in EtOH (2.0 mL) was stirred at 40 oC for 15 h. After completion of the reaction, as indicated by TLC, the removal of solvent and purification by flash column chromatography (hexane/EtOAc= 5:1~3:1) were carried out to furnish the corresponding products 3.
At the same time, in my other blogs, there are other synthetic methods of this type of compound, 5-Bromo-1-methylindoline-2,3-dione, and friends who are interested can also refer to it.
