Adding a certain compound to certain chemical reactions, such as: 611-09-6, name is 5-Nitroindoline-2,3-dione, belongs to indolines-derivatives compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 611-09-6, Application In Synthesis of 5-Nitroindoline-2,3-dione
Mg(ClO4)2 (0.1 g) was added to a mixture of isatin (2 mmol), and dimedone (4 mmol) in aqueousethanol solution (50%, v/v, 5 mL), and the resulting mixture was stirred at 80C for 10-12 h. Upon completion of the reaction (TLC, Ethyl acetate/Petroleum ether = 1:4), the mixture was allowedto cool to room temperature. The resulting solid was filtered and washed successively with water(2 30 mL) and cold aqueous ethanol (2 1 mL) to afford a crude product, which was recrystallizedfrom EtOH to afford the pure product 3. Some insolubility could be observed in the refluxing ethanolduring the recrystallization process, which should be filtered when hot.
